Therefore...
Therefore, the possibility of changing oneself exists for everybody until the end of his life. In other words, there is no certain conclusion and end of every person’s life story and his destiny cannot be considered as being predetermined. Here, we proceed to another issue and that is, the indescribability of man. Every phenomenon, in our analytical view, possesses two facets: one is its ‘being’ (“is”) and the other, its ‘manner’ (“what is”).
For instance, an apple as a concrete reality has subsistence and along with this subsistence, the essence of its nature can be included and expressed in its description. Therefore, all terrestrial things possess subsistence and disposition, which in philosophical jargon are called ‘existence’ and ‘essence’. Now, let us see what the nature of man is. The existence of various explanations on the essence and nature of man only indicates the divergence of views on this issue.
For example, after stating the manner of man’s creation, God, the Most Sublime, praised and named Himself as the most Excellent Creator.[7] Yet, at the time of giving account to the trust, which the heavens and the mountains trembled for taking responsibility but which man shouldered, God introduces him as iniquitous and imprudent.[8] If we pursue this trend, we will encounter other descriptions and explanations.
As a result, we can say that man has various explanations, or is essentially indescribable. Man is all of these; but at the same time he is beyond all descriptions. In a sense, man is the only terrestrial creature that has neither definite essence nor a specific limit, and he has such potentialities and capabilities that one’s nature cannot be foretold before their realization. According to the existentialists, all beings possess a definite nature that could be made known to them in advance.
However, a human being is the only creature whose existence takes priority over his nature, or he ‘builds’ his own nature. John Paul Sartre,[9] the most famous expounder and exponent of existentialism, opines on this matter thus: Man’s conception of himself is not only what he has in his mind; it is also what he wants of himself. It is the concept (of himself) that he exhibits after its manifestation in the world of existence. It is that which he seeks from himself after moving toward existence.
Man is nothing but what he makes of himself. This is the foremost principle of existentialism.
