“The time in which a person lives gives him the opportunity of knowing himself as a moral being, engaged in the search for the truth; yet this gift which man has in his hands is at once delectable and bitter. And life is no more than the period allotted to him, and in which he may, indeed must, fashion his spirit in accordance with his own understanding of the aim of human existence. The rigid frame into which it is thrust, however, makes our responsibility to ourselves and others all the more starkly obvious. The human conscience is dependent upon time for its existence.”
Andrei Tarkovsky, Sculpting in Time: Reflections on the Cinema
