When air becomes music: An example of how biology deals with data

Data Overflow



This article is mainly based on the book  » This is your brain on music  » by Daniel J. Levitin, and slightly on the work of Oliver Sachs. I tried to imbue it with a personal touch but at the end of the day I’m just standing on the shoulders of giants and I would be remiss if I didn’t urge you to go back to the source, where you would find the real deal.

I always wondered, like with the chicken and the egg, whether the music mind was an intentional result of the evolutionary process that any currently existent physiological function undergoes like the perception of colors, sounds, and scents for instance, or was it a product of some ingeniously discovered brain hacking, maybe something similar to drug-induced frenzies and hallucinations. It is surely a curious affair, but whatever the answer might be one thing remains certain: the human brain is equipped to perceive and eventually respond to music somehow differently than it would to normal sound.

We know that one remnant feature of our mammal predecessors’ lifestyle is the reflex of responding to a specific sound, or at least some inherent element defining and distinguishing it. We know that humans (as well as a considerate number of other animal species ) for example are wired to react to particular auditory stimuli, a baby’s scream, for instance, is set to trigger a reaction from the mother. This kind of response is very interesting to monitor with a functional MRI where you actually can see defined parts of the brain activating along with the infant’s cry.

Some animal species tend to be startled by the noises characteristic of their natural predator, so even if isolated shortly after birth and thus never having heard it before, a fight or flight reaction is still triggered. It is an innate reaction, it’s simply wired in. Music, on the other hand, seems to work on a deeper level, it’s much more complex and it relies on the brain’s ability to recognize intricate patterns and then to relay the right commands to the right structures. Unfortunately, the exact mechanisms of it all are not fully understood at the moment, and saying that the science explaining the musical mind is vast can only be an understatement, so I doubt that I can in this relatively short article lay down more than a fraction of it.

Yet, that doesn’t matter since that tiny fraction was enough to have me in awe, and hopefully so will you. I’m here trying to share a glimpse of what makes music magic, from its fundamental building blocks to the way it is processed in the brain and hopefully, together we would answer life’s most critical questions: why do I feel blue when I listen to the Smiths? Why do I feel the urge to dance when Soft cells ‘version of « Tainted Love » is being played? And why can’t I help but sing along to « Bohemian Rhapsody »?

It is almost impossible to set a value to a given perception since it is in a sense the very definition of reality, and so nothing can get more subjective than that. This doesn’t mean we can’t work with that notion we might be able to judge its usefulness in a given environment. So for the sake of the argument let us consider the average healthy human as a point of reference and let us establish our notion for perception: the power of perception. By definition, the average healthy human would have a mind perceiving just a fragment of all reality and that fragment is sufficient to survive and thrive in ( and only ) in that same reality.

We decrease that power of perception and we get cases like blindness, deafness, or more fringe and exciting complications. We increase it and we could get either superhuman-like abilities or very debilitating conditions. With that said I’m taking the liberty of establishing a further notion, let’s call it meaningfulness of perception, this would be the optimal perceptual power, which extends beyond the average healthy yet never inconvenience a person’s living.

Now we get to ask a question: what makes a perception meaningful? Perception is as meaningful as the amount of information held by a signal, as the capacity of the sensor to extract that said information, and then how well it is integrated into a whole. We could compare this last part to processing in a computer. This principle is important to understand since everything that exists can be in principal converted into « data » as long as you have the right sensor and the right way to process everything, or at least that’s the way nature managed to have living things around for so long.

Now, humans changed that when they started to mess around with the signals, eventually they succeeded to bypass the source and either duplicate it or create a new one, here of course I’m talking about inventions as simple as speakers and headphones. So when we talk about music and the phenomenon behind it we are dealing with a pretty meaningful perception of what partly constitutes reality.

To begin understanding music we have to strip it down to its core element: the sound wave. Sound propagates itself as a wave, which is interestingly enough a very efficient vessel for information. To dive a little bit deeper, try to visualize dropping a pebble on a smooth water surface, ripples would form, circular waves that spread outward. Those waves represent the trajectory of energy inside the water, moving in an oscillating manner pushing water particles on their way.

Now instead of using the water and the pebble, we struck a guitar string, the same thing happens, energy starts to move around. The shape of the string limits its propagation to two dimensions instead of three but the principle stands the same. Now since air too is made of particles that can be pushed around, the string will whip some of its energy into the air which allows the propagation process to take place there, again abiding by the same principle. Now a wave holds properties the most important being speed, frequency, and intensity.

Speed depends on the material inside which it exists, that’s why for example the speed of sound is more or less a constant and that’s why inhaling helium ( A gas 3 times less dense than air ) increasing this speed makes your voice sound funny. Frequency also depends on the properties of the material, so in a guitar string, it can be altered by loosening or tightening, when we later get to talk on a less physical and more conceptual level we will refer to it as pitch. Intensity is what is seen mathematically and intuitively as the height of the wave, it depends on how hard you pluck a string, this parameter defines loudness.

Other elements characterizing a sound are also derived from the wave, so it’s even more informative with « data » such as contour, rhythm, tempo, timbre, spatial location, and reverberation. These are not technically intrinsic to the wave itself but they describe its state in the outside environment and its interaction with a multitude of similar or different waves. Contour describes the overall shape of a melody, which translates to whether sound seems to go up or down, to visualize the difference I propose the word  » EETA » for up and « ATEE » for down.

This effect is coded as a difference between two pitch frequencies in the melody. Rhythm, briefly, is the relationship between the length of a note and another. You can argue that music, stripped of its rhythm, goes back to being just sound. Tempo is the pace of the music piece or if you want, it represents how fast a musical piece is being played, it must not be confused with rhythm since both vary independently. These last two play a major role in the emotional impact a piece of music possesses.

Timber is the thing that distinguishes one instrument from another. You hear a piano, you’ll know it’s a piano and not a guitar or a violin, even when it is the exact note is being played. This type of auditory data is what allows us also to recognize familiar voices and distinguish thunder from rain. Since two identical guitars would have the same timbre it is no surprise that this parameter is also related to the material from which emanates the sound. Reverberation as explained by Daniel J Levitin  » refers to the perception of how distant the source is from us in combination with how large a room or hall the music is often referred to as « echo » by laypeople, it is the quality that distinguishes the spaciousness of singing in a large concert hall from the sound of singing in your shower ».

This element exploits neural circuitry intended to perceive sound in the context of space and adds an undeniable emotional value to music. A great example of this is the work of Bon Iver mastered reverberation creating this hauntingly beautiful atmosphere in songs like  » Re: stacks » or  » Flume « .
The elements I just enumerated qualify as fundamental perceptual attributes. When they are put together or processed by the brain higher level concepts emerge: meter, harmony, and melody.

Frankly, my explanation of these lower-level concepts was just a watered-down version of the whole deal, each of those would have taken pages to fully develop, liberty that I lack. But as a compromise and I suppose as the necessity dictates for the sake of a more intelligible read I’m going to attempt expanding on some of them.

While frequency defines the physics of a sound pitch refers to its perception. This can be compared to colors and wavelengths. Audible sounds range from 20Hz to 20,000 Hz but the acuity of the hearing withers at the extremes. Even though we theoretically have an infinite number of pitches each corresponding to a different frequency ( Pitches exist in a continuum of audible frequencies ), we would only notice a change, a transition from one pitch to another if the difference exceeds a certain threshold. That threshold is not the same for everyone and it is linked to the sensor cells ‘density that we would find in a specialized ear tissue.

As an estimate, a human being can’t distinguish two pitches closer than one-tenth of a semitone. If you never studied music before, you must be confused about the semitone, bear with me, I’m getting to it. So we are all familiar at least somehow with the musical scale or more commonly known as the Do Re Mi. A modern piano holds 88 keys, 52 whites and 36 black, let’s forget about the black ones for this one.

If you start hitting one key after the other in the order you will notice that after 7 hits what comes out is a slightly different variation of the same notes you just played. And most people know that after you go from Do to Si you go back to Do. So something about this is cyclic. But the Do of the first cycle doesn’t sound the same as the one after and the one before it, it might seem higher or lower. In music jargon, we call each cycle an octave.

Here’s the wizardry behind that: For a given octave each note is defined by a pitch frequency meaning that if we take two pianos and we try to get them to sound the same we would tighten their strings in a way that when hit they vibrate at the same frequency. That’s what tuning means, by the way, setting the instrument to vibrate in specific frequencies. Let’s take a random frequency of 25 Hz for example if you wanted to hear the same sound at a different octave you have to multiply it by an integer ( N * 25Hz ) which would give us 50Hz, 75Hz, 100Hz … In the western musical traditions an octave is divided to 12 semi-tones, it’s an arbitrarily chosen unit of time.

The pitches chosen to form the musical scale were arbitrarily picked, but not at random. You see if you take a note and the one just after it in a standardly set and tuned instrument you’ll notice each time an increase in the frequency at a constant rate of 6%. That makes the notes equally spaced in our ears even though they are not ( The distance between Do and Re is Do+Do*6% while the distance between Re and Mi is Do+Do*6%+Do*6% *6% ), this is made possible by the brain’s ability to recognize proportional change, which is if you think about it very impressive.

The sensitivity to the spacing between notes is especially useful when building melody. Melody, in a nutshell, is the shape of the music, it doesn’t care about pitch individually but the relationship between those pitches, the distance between them. To help you see it, imagine you’re holding a guitar. You have your fingers on any given combination of frets and you strum the strings in any given order, now you slide your fingers without changing that combination you just transfer it as it is. If you didn’t mess up my commands and strum the strings in the same order you would hear something very similar to the first, the element responsible for the similarity is the melody. When you hum a song, you hum its melody.

At this point, you should be confused, if the pitch frequency sets the note and if generally speaking two different types of instruments could access the same frequency, why don’t they all sound the same, how the heck do we explain timbre?

In the 50s a composer named Pierre Shaeffer experimented. The first recorded the same musical piece using different instruments then edited out the first instant of every note. That instant corresponds to the action responsible for the initial transfer of energy that we talked about earlier, dropping the pebble, strumming the string, it could also be hitting a bell with a hammer or whatever we use to play an instrument, we call it the attack. What Shaeffer found out after piecing everything together is that without that attack people could not recognize the instrument in play. Cool right?

Explaining these strange results requires revising the notion of how pitch manifests itself on a non-theoretical ground. When I said a string vibrates at a specific pitch I undersold it since in reality, it vibrates at several frequencies all at once, this is a physical property to all things. And if you ever heard the word harmony and never bothered checking its meaning well it is somewhat that, a sound made of layers of pitches. In a harmonious sound, the lowest pitch is referred to as the fundamental frequency, the rest are collectively called overtones.

The overtones are always integer multiples of the fundamental frequency, so if we have a fundamental frequency of 50Hz, the overtones would be 100Hz, 150Hz, and so on ( Even though sometimes it would be just approximately that multiple ). When dealing with such a multi-layered sound the brain, who first detects each pitch separately, synchronizes the neural activity associated with each one to eventually create a unified perception of the sound.

We must never forget that we are still talking about waves, and these have intensity and that determines loudness. Considering that the loudness of each could vary independently we end up with an infinite number of combinations. We call those combinations the overtone profile, we can look at it the fingerprint of an instrument’s characteristic sound. Nowadays we can isolate these overtones and create basically from scratch new sounds never heard before and even impossible to find in nature ( And this is just one way to do it ).

In addition to the overtone profile, two other elements help shape the singular aspect of a sound: attack and flux. The attack allows us to understand the Shaeffer experiment: When we introduce energy to a material, it propagates as a bunch of waves, but with frequencies that don’t follow the proportional relation the same way overtones do, this only continues for a short time before stabilizing into a pattern associated with an overtone profile. This means that a strike of a bell, the strumming of a string, and the blowing inside a whistle impacts in the first instant, the way the instrument sounds.

Flux on the other hand describes the way a sound changes over time after it started. If you’re interested in the impact of timbre in music, I can’t find a better example than  » Bolero » de Ravel. Ravel had brain damage and by the time he wrote it, he was pitch-blind. In this piece, you’ll notice that virtually every element in the music keeps repeating but the timbre. You would think repetition would make it redundant and boring, but with each time a different instrument plays the same melody, it just keeps on coming and it is simply brilliant.

Okay, all that sounds nice and all, but as long as it is airborne and unprocessed, music is yet to be born. Faithful as we are to the Socratic method, we ought to ask another question: How does vibrating air become music? Well, the phenomenon starts when the wave finds its way inside the ear and hits the cochlea. This is that specialized tissue I mentioned earlier, it’s essentially a membrane covered with auditory sensor cells. You can think of them as tiny joysticks, when the air particles hit, they wiggle and when they do, they send signals to the brain.

The mechanisms underlying how we get from mechanical energy to an electric nervous signal, are mostly biochemical, and that, so not to say boring is certainly an acquired taste, so let’s just move on to something sexier: neurons. We can find neurons or neuron-like cells in numerous structures all through the body, although it hardly compares with the insane concentration we find in the brain. These cells are interconnected, there are nearly a hundred billion neurons inside of a human brain and they form networks so complex that it allows for a computational system potent enough to support the emergence of thoughts, perceptions, and consciousness. Seeing that music falls under the realms of perception we will focus on how that translates neurologically.

Perception is said to be an inferential process and unless you’re a nerd I doubt that makes sense to you. Let me put it differently: Perception, as achieved by the brain, could be summed up as experiencing what is there and what could be there. The second part stems from an evolutionary attribute we got from our ancestors’ struggle with things that could kill them, so when you look from a distance and you detect something strange, maybe a pixel that doesn’t blend with the rest, to urge you to run away instead of standing there trying to figure out whether it’s a darker bush or crocodile coming to get you, your brain will show you a crocodile.

Another role for this inferential way of doing things is dealing with data that gets lost in transit. When information is missing the brain calculates what could have been there and then replaces it. Of course, to attain an end-product unifying the real and the probable, two different approaches to processing come into play. The first -dealing with what is there- is called bottom-up processing and it relies on two steps: A process of feature integration that consists of decomposing the signal and extracting the lower-level perceptual elements, for instance, the building blocks of music. The other is a process of feature integration, here, since we have distinct elements, the brain deals with each separately, but all at the same time, managing several tasks all at once.

This phenomenon is particular to the brain which utilizes parallel neural circuits. This is also why people with brain damage or a congenital neurological dysfunction might fail to perceive one feature of music but have no problem with the others. This approach is considered as low-level processing and thus handled by structures in the brain that evolved relatively earlier than more sophisticated counterparts that consequently manage higher-level processing. That is, higher-level processing retrieves data from the lower one and crafts a further understanding of what you’re working with, thanks to that we can look at a succession of weird-looking shapes and recognize words.

The second, the one that shows us what could be there, is called top-down processing, it takes place in the frontal lobe. This function gets constantly updated with information coming from the lower-level processes and other parts of the brain so that in the end it predicts what is more likely to happen. In the case of music that information would be what you already heard in the same song, what you remember of similar songs, if not it would be songs from the same genre and style, even information less related to music and more to the environment around you is taken in account.

The reason we are susceptible to auditory and visual illusions can be found in the dominance of the top-down processing over the bottom-down processing, this practically means that the predictions somewhat transpose the perceived reality. What comes out of both is integrated into higher-level processes which give us in the end a constructed perception, in our case music. Exploiting the balance between the predictable and the unpredictable is very important when trying to write thrilling music. The unexpected is associated with novelty which turns into excitement, this only applies for reasonable doses, abuse it and you create something the mind can’t follow and so it becomes irritating.

For the frontal lobe to make a prediction it partly relies on retrieved music-related data from somewhere, implying a storage solution for musical information. This brings us to the wonders of neuroplasticity, to state its fundamental thesis briefly, neuroplasticity refers to the fact that when neurons activate they change, both morphologically and concerning the connections they establish within a network. This means that these so-called networks keep transforming again and again. Memory is said to be a function of those connections. This may not sound impressive said like that but you must remember that a human brain holds 10 hundred billion neurons, so the number of possible combinations you could attain is difficult to grasp.

Seeing that we are talking about the storage of music, I might as well share with you a phenomenon so cool it’s almost unbelievable: Musicogenic epilepsy. Epilepsy is essentially neurons that start firing pathologically, this causes neurological circuits to activate and can cause behavioral symptoms such as seizures. In some rare cases, the faulty wiring in their brain affects circuits where music is stored, causing patients to hear music, in their heads, clear as the first time they experienced it.

To end this article I must express how grateful I am that music exists. It is one of the greatest gifts that life bestowed upon us and unless new evolutionary data emerge it is a rare sign of nature’s unconditional love for humanity. At the risk of stealing a lyric from an old Irish song, » For sinking your sorrow and raising your joys » nothing compares to it, so as long as your brain function is intact and your spirit is alive accept music not as simple entertainment but as a way of interfacing with a reality that we still can’t fully comprehend.

الإنسان عدواني بطبعه






   Dark في الحلقة الثالثة من الجزء الثاني من      

كلاوديا تيدمان قالت لإيغون تيدمان  في عمر 9 سنوات وأعادت نفس الجملة بعد 66 سنة « أنت طيب أكثر من اللازم ، العالم لا  يستحق شخصا مثلك      

في إشارة من السيناريست أن طيبة هذا الشخص و صفاء قلبه لم تؤثر عليهما عواقب الحياة و قسوتها و شر العالم الخارجي و قساوته 

فهل حقا يستطيع الإنسان أن يحافظ على نقائه الداخلي رغم كل هذا ؟ و هل أن الإنسان يولد نقيا أصلا من كل الشرور ؟

و هل أن الخير و الشر قيم ثابتة لدى كل إنسان ؟ و هي نسبية بين الشخص والآخر ؟ 

هل هناك حقا  أشخاص لا يستحقهم العالم ؟ 

أ هذا يعني أن  مقاومة شرور العالم تستوجب و لو القليل من الشر المضاد له ؟ 

هل الخير يستحق عالما أخر خالي من الشرور ؟ 

أم أن العالم يستحق فقط الخبيثين ؟ 

و ما النتيجة لو قمنا بعزل الخير عن الشر ؟

ولكن أليس من العدالة الكونية أن يلقى كل شخص جزاءه ؟ 

و أين العدالة في أن يدفع شخص طيب ثمن آلام  هو أصلا لم يتسبب فيها ؟ 

و إذا افترضنا حقا أن كل شخص سيلقى فعله فالطيب لن يتعرض إلى عراقيل أو شرور، ما المغزى من حياته إذن ؟

و لماذا وجد الشر أصلا، ما الحكمة من ذلك ؟

الإنسان عدواني بطبعه هذه هي خلاصة المدنية الأشمل 

حيث أظهرت  تجربة بول بلوم و كارين واين أن الأطفال سويين في سلوكهم حيث ينحازون للخير في أغلب الأحيان،و لكن من جهة أخرى أظهرت التجارب أن صفة الأنانية تولد مع الطفل منذ نعومة أظافره أيضا، أظهرت التجارب أن الأطفال يولدون مع صفات أخرى مثل العدائية ، ما يعني أن العائلة لا تصنع العادات فينا بل دورها ينحصر في تنمية العادات المولودة معنا أو محاولة محاربتها.

يرى الأشخاص ثنائية الخير و الشر، كل بطريقته و كل من مكانه الشخصي نسبة لمكان الأخر 

يرى الضعيف الشر في القوي 

يراه الفقير في الغني 

أما نظرة الطرف المحايد  الذي لا ينتمي لمجال الطرفين  و لا تنطبق عليه قوانين طبيعة العلاقة بينهما سيحلل الموقف بالعاطفة 

.الآلام يمكن أن تتسبب في خفض قيمة الإنسان 

في زمننا هذا المادة طغت على كل القيم و لم تترك لها أي مكان 

لكن السؤال الأهم هو لما يلجأ الإنسان لإيذاء أخيه الإنسان و ما الذي يدفع الشخص لإلحاق الضرر بشخص آخر ؟

يمكن أن تكون الإجابة على هذا السؤال إحدى هذه 








و ربما الحب ، حيث قال نيتشه ذات مرة « ما يتم فعله في سبيل المحبة دائما ما يتعدى حدود الخير والشر

و هي خصال متجذرة فينا تولد مع كل إنسان 

ما الشئ الذي يجعل شخصا ما يكون شريرا ؟ بماذا يشعر شخص عند إيذاء شخص آخر ؟ 

إما أنه يشعر دائما بأن ما يفعل هو الصواب ، أو أنه يعرف أنه على خطأ، الهدف أهم بكثير من الشخص ومشاعره  يبدو الأمر كإشباع رغبات الشر بداخله، فقط القيام بتلك الأفعال يحرك فيه مشاعر الفرح الجامح و نشوة الإنتصار ،تحت شعار : الغاية تبرر الوسيلة 

دعنا نقل أن أسباب الأفعال البشرية متنوعة و متعددة و عادة معقدة 

.يمكن أن نتفق مع فرويد في أن معظم أفعال الفرد العدوانية و رغباته الجنسية ودوافعه المكبوتة  تحت تأثير الهو اللاواعي ، الجزء الأكبر من عقل الإنسان

.حيث أن أناه الواعية هي الجزء الأصغر المسؤول على قرارات الفرد على المدى الطويل و التي تتطلب تفكير واعي

وبالرغم من أن كلاهما تحت رقابة الأنا الأعلى و هي عبارة عن تصورات المجتمع و محاكماته الأخلاقية إلا أن كبح جماح الهو الطاغية يبقى نسبيا و يختلف من فرد إلى أخر, ما يؤكد طبيعة الإنسان العدوانية 

نأخذ كمثال سلك الشرطة و السجون لو ساءت الأقدار و إقتربت من ذلك الميدان ستسمع كثيرا كلمة: ما يجعل الأمر صعبا هو أن يقصو الناس على بعضهم البعض

الرفقة الحسنة دائما ما تكون جميلة حتى في أصعب الحالات نتحدث هنا عن سجن ، سلب للحريات وما الأصعب من أن تحرم شخصا من حريته بل أسوأ من  .ذلك تطعمه طعام الحيوانات تأبى أن تنظر إليه درجة شديدة من الإذلال في المعاملة و في الألفاظ

حتى الخير الظاهر لنا يبدو أنه لم يعد نابع عن نقاء روح الإنسان بل إنه إستحسان و فعل صادر من شخص يتودد و ينتظر مقابل و حتى إن لم يكن كذلك فهو يقدم خدمة لشخص متأكد كل التأكد أنه لو طال الزمان أو قصر لا بد و أن يقع في حاجة إلى ذلك الطرف المقابل 

لم يعد يوجد من يحسن لشخص أقل منه غنى أو سلطة 

و أصل الأمور أن الأقل شأنا يكون في حاجة لمن هو أعلى شأنا

نستغرب عادة من الظواهر الإجتماعية و الأمراض النفسية الشائعة في المجتمع و نغض بصيرتنا عن تصرفاتنا و معاملاتنا تجاه الناس 

لنأخذ كمثال أشهر ظاهرتين الوحدة والاكتئاب

الوحدة ألا يمكن أن تكون حالة إنسان تعرض إلى الأذى و تحمله لدرجة أنه لم يعد يستطيع تحمل أي إنسان ، وجد الرفقة في الظلمة و السكون

بالنسبة للاكتئاب أيضا هناك نسبة كبيرة من الحالات وصلت لهذه المرحلة بسبب خيبات الأمل المتكررة ، خيبات أمل من نوع صداقة ، عمل أو غيره

الأشد سوءا من الشر ذلك الخير الذي يخفيه ، ما أقصده ذلك الصديق اللطيف الطيب -و كل تلك العبارات النبيلة- الذي يخفي بداخله مكرا و رغبة جامحة في .إيذائك و إصابتك بمكروه

يا لها من كذبة كبيرة ؟  الكذبة التي أحببناها جميعا 

أن الحياة ستظل على هذا الخير 

أجل تصورنا بأن كل شئ سيكون بخير 

هكذا يخيل للجميع

منذ ولادة الإنسان و من حوله والده و والدته و بقية أفراد العائلة جميعهم يبتسمون في وجهه أو ربما البعض و يريدون اللعب معه و مداعبة أصابعه ، حتى يكبر قليلا ربما يقل عدد المهتمين لكن الفضاء الذي يوفره له والداه غاية في الرفاهية ، إهتمام مفرط و كل الطلبات تلبى على أحر من الجمر ، حتى يصل إلى سن السادسة وقت الدخول للمدرسة هناك ستجد معلميك و أصدقائك و دائما كل شئ بخير حتى تصل إلى مرحلة المراهقة هنا يمكن للمرء أن يبدأ في النظر .للموضوع من زاوية أخرى

و هناك من يعيش المعاناة منذ نعومة أظافره من ترعرع وسط الحروب و المآسي جدير بالذكر أطفال غزة أولئك الذين كبروا على المرارة وصوت القنابل بدلا من صوت الدمى الناعم

مسألة أخرى لا تقل أهمية ، لو أن الإنسان من دون رقابة ؟ و لا تسلط عليه عقوبات هل سيبقى ذلك الإنسان الخير ؟ أم أنه سيظهر شروره الداخلية ؟ 

ربما يكون الإنسان أذكى من أنه يتصرف على غريزته و يحارب من أجل بقائه و لهذا وجد مفهوم العقد الإجتماعي الذي ظهر مع فكر الأنوار 

و لما يتعاطف الإنسان مع الشخصيات الخيالية في المسلسلات رغم أنه يشاهد ما تفعله من شرور ، ربما يتعاطف الشخص معهم لأنه يعلم أن مشكلته الشخصية ليست في كونه شرير و إنما الظروف جعلته يرتكب أخطاء و بهذا يمكن أن نقول أن كل إنسان بداخله شر ينتظر الظروف الملائمة التي تحركه و تكون .مبررا أما العالم الخارجي

لكن بالنسبة للمرضى النفسانيين و كل من لديهم مشاكل بيولوجية قادرة على التأثير ولو بنسبة صغيرة على أفعالهم،  هل نحن قادرون على  محاسبتهم على أفعالهم ؟ 

بل هل نحن حتى قادرون على تعريف أفعالهم على أنها خير أو شر ؟

ربما للمشاهد العقلاني هي كذلك ، لكن بالنسبة لهم هي تبدو مجرد ممارسات يومية لا تندرج ضمن جدول الأفعال القابلة للتقييم ( أي يجازى على الخير و يحاسب على الشر )  هي بالنسبة لهم كشرب قهوة في الصباح  أو التجول في عشية يوم ربيعي

حينما نتحدث عن الشر عادة ما يقودنا هذا للتساؤل، هل أن الإنسان مسير أم مخير ؟ 

و الإجابة عن هذا السؤال ستقودنا للعديد من الأسئلة المتفرعة 

لكن لسائل أن يسأل هو الله سبحانه و تعالى كيف يحاسبنا على أفعالنا لو كنا مسيرين ؟

ربما المشكلة فالسؤال أنه يقدم لك خيارين للإجابة في الوقت الذي تكون فيه الإجابة أكثر تعقيدا من ذلك ، يمكننا أن نشبه الحياة بلعبة الأوراق نحن نبدأ اللعب بأوراق لم نختارها و تلك هي الظروف ولكننا نقرر مصير اللعبة بقرارتنا ، فلنأخذ مثال الفقير (ظروف) لكن بيده القرار إما العمل أو السرقة أو كيف أن الله يعلم الغيب أي أنه يعلم ما سنفعله في المستقبل فكيف سيحاسبنا يوم الآخرة ؟

و إذا كان كل شئ مكتوب فأين هي حرية الإختيار ؟

 مثل الأستاذ الذي يعلم من يدرس بجد و من يأتي لإضاعة الوقت أي سلوك الطلاب هو من يمكنه من أن يتنبأ من سلوك بأن يتنبأ بمن سينجح و من سيرسب و يمكنه من معرفة من سيدلس يوم الإمتحان

هذا هو القدر فهل بإمكان الطالب الذي رسب لوم الأستاذ على أنه تنبأ بذلك ؟

بمعنى  أنت لديك خيارين  « أ » و « ب » إخترت أنت أ ألله يعلم أنك ستختاره مسبقا و لكنه أتاح لك حرية الإختيار كل ما في الأمر أن الله يعلم إختيارك مسبقا فلو أجبرنا على المعصية لما وجد العقاب و لو أجبر نا على الطاعة لما وجد الثواب  

ألا تأتيك لحظات و تفكر ألف مرة قبل أن تقبل على قول أو فعل شئ ما فكيف تقول أنك مسير إذا ؟ لو كنت مسير لما أقدمت على ذلك الشئ دون التفكير ولو لمرة  فلنعترف جميعا إذن أننا مسؤولون على نسبة كبيرة من أفعالنا و أننا نستحق أن نعاقب على كل أخطائنا 

لكن و ختاما و حسب بسيكولوجيا الأنانية 

فبالرغم من أننا نفعل خيرا لغيرنا فهو نابع من دوافع أنانية أي نحن لا نقوم بالخير لأجل من قمنا به لأجله بل نقوم بذلك لأجلنا طمعا في الأجر و لكي نشعر بالسعادة تلك السعادة التي نشعر بها و التي تكافؤ بها عند مساعدتنا أو قيامنا بعمل صالح ما يجعلنا نعود لتجربة بول بلوم و نظرية الإنسان أناني بطبعه و هكذا يكون أتقانا أكثرنا أنانية و لعل غالبيتنا إستمع لمقولة : أنا مستعد للمخاطرة بحياتي و إنقاذ طفل من الموت في الفيضانات فقط لإرضاء ضميري و لكي لا أشعر بالذنب

ما يعني أن الإنسان يدخل في عقد إجتماعي ليس من أجل كبح جماح أنانيته بل من أجل حماية نفسه من أنانية غيره
