Question

You once wrote that existentialism is not a philosophical doctrine.
Isn’t the question of the meaning of life, which is part of the definition of this doctrine [as can be seen on Wikipedia], a philosophical question?
It seems to try, ostensibly, to clarify an objective truth [and not deal only with a person’s feeling]. Does our life have meaning, and if so, what is it?
It seems to me that you ignored this in your column [you only wrote that if there is some philosophical question that the existentialist writer deals with, it is only incidentally, and that really is a philosophical question, but it is not part of the core of this thought. But as I understand it, the question of the meaning of life is indeed part of the core of this thought]
