This was a refreshing and honest treatise. Lately, I have been pondering if we have free will and what consciousness is. I read some modern books on this (Sam Harris, Daniel Dennett, amongst others) and it seems to me that even though our modern day knowledge about these subjects - thanks to neuroscience and cognitive psychology - is much much further than the knowledge natural philosophers like Descartes and Spinoza had access to, the issues are still not solved. I even think that with all these new insights, the issues at hand are much more obscured.
Therefore, it was enlightening to read Schopenhauers treatise. This is a man who faced up to the facts, and accepted life for what it is: enduring suffering and hardships. Leading a happy life means (for Schopenhauer at least) avoiding suffering as much as possible and giving up striving for things. This is a philosophy I can subscribe to.
Now, on to the subject. According to Schopenhauer (1) freedom is the abscence of necessity (something is free as far as it isn't caused (i.e. necessary) by some other thing and (2) consciousess has to be divided in (2a) our mental cognitive faculty of consciousness (i.e. beging conscious of objects in reality) and (2b) our self-consciousness (i.e. the will).
Self-consciousness is nothing but the will to do things. There is no will to will, or will to will to will, etc. This would only lead to an infinite regress without explaining the will itself. The will is caused by (1) our character and (2) our motivations. Our character is determined (genetically and environmentally so, as a modern day philosopher would say), therefore not free. Our motivations are caused (in the end, although very long chains of causation are possible) by objects in reality. Therefore, our motivations are determined as well. This leads to the conclusion that objective freedom doesn't exist. We do what we will, and this is who we are.
Consciousness is nothing but the cognitive faculty that we are born with. This faculty lets us perceive the world around is and comes equipped with the notions of time, space and causality (Kant). It is these notions that we use to perceive the world around us. Causality comes in different forms: mechanistic causality (physics, chemistry), causation by stimulus (plants, vegetative actions of animals, including humans) and causation by motivation (the intelligence of higher animals, where humanity is the 'crown jewel' of rationality). These forms are all deterministic (causes precede effects), but the higher up you go, the longer the chains of causations become and the harder it becomes to see the causation at work. This is in effect the illusion we have of our own freedom. We do what we will, and this will is determined by our character and our motivation. This motivation in its turn is determined by our perception of the concepts (experience and education, or lack thereof).
Towards the end of his essay, Schopenhauer falls back on Kant, to save freedom. This is sad, because it seems like a leap of faith and goes against the earlier 2/3 of his essay. According to Kant, the objective world can only be verified empirically (i.e. the phenomenal world), but there's a subjective world where the thing-in-itself is located (i.e. the noumenal world). It is in this subjective realm that Schopenhauer finds his freedom.
To cite Schopenhauer on this conclusion: "In a word: man does at all ttimes only what he wills, and yet he does this necessarily. But this is due to the fact that he already is what he wills. For from that which he is, there follows of necessity everything that he, at any time, does. If we consider his behavior objectively, i.e. from the outside, we shall be bound to recognize that, like the behavior of every natural being, it must be subject to the law of causality in all its severity. Subjectively however, everyone feels that he always does only what he wills. But this merely means that his activity is a pure expression of his very own being. Every natural being, even the lowest, would feel the same, if it could feel.
Consequently, my exposition does not eliminate freedom. It merely moves it out, namely, out of the area of simple actions, where it demonstrably cannot be found, up to a region which lies higher, but is not so easily accessible to our knowledge. In other words: freedom is transcendental." (pp. 98-99).
I follow Schopenhauer a long way in his argument, but when he starts to call in a subjective freedom, I quit. This is merely passing the buck. It says nothing and is (in my opinion) a superfluous statement. In the fourth chapter, Schopenhauer gives the example of a Spanish murderer who is to be executed the day after, who claims that even though he would wish he wouldn't be executed, if the English court would set him free, he would murder again. This is a perfect illustration of the implications of Schopenhauers view on free will and consciousness, and one of the most honest ones at that. We do what we will, and that makes us who we are. Our actions are determined by our character and our motivation, which both are determined in their turn. Punishment is nothing but raising the stakes for bad people, making them feel harsher consequences if they continue with their actions. The reason we punish criminals is to deter others from behaving the same as these anomalies.
On a side note: in chapter four Schopenhauer shows his true, atheistic, face by rubbing theologians in their face with the impossibility of free will. Either god created us the way we are, thereby rendering punishment for sins useless and senseless and displaying his own evil (so a 'good god' is not possible), or he gave us free will because he is not able to create a perfect world (so a 'omnipotent god' is not possible). The notions of god in Christianity, Islam and Judaism presuppose free will. If free will is an illusion, those creeds are illusions. Therefore, atheism is left. Brilliant argument!
