Plato's Primary Causes

He attempts to try to reach the audience and tries to explain his reasoning for letting go of the primary causes, he believes if one is to let go of the reasons of the natural man's desires one may enjoy freedom.
These primary causes are described by Aristotle and Plato as follows:
The material cause: aspect of the change or movement which is determined by the material that composes the moving or changing thing
The formal cause: "the form" the account of what it is to be
The efficient cause: the primary source of change or rest
The final cause: the end, that for the sake of which a thing is done
Another example of the Underground Man's rebellious nature against reason is such:
"Where are the primary causes on which I can rest, where

are my bases? Where am I going to get them? I exercise thinking, and, consequently, for me every primary cause immediately drags with it yet another, still more primary one, and so on ad infinitum."
(Dostoyevsky 14)
Here again we see how the Underground man loves the idea of free thinking and believes the primary causes are nothing more than dead weight.
It is the Natural man who surely will be able to answer these causes easily and therefore use reason to make sense of the natural world. The Underground Man however cannot answer these questions because he is filled with doubt due to his idea of free will and his hyperconsciousness.
Hyperconsciousness leads to doubt as it is doubt that makes one question ones decisions, which leads to a state of conscious inertia.
