Playboy: If life is so purposeless, do you feel its worth living?
Kubrick: , for those who manage somehow to cope with our mortality. The very meaninglessness of life forces a man to create his own meaning. Children, of course, begin life with an untarnished sense of wonder, a capacity to experience total joy at something as simple as the greenness of a leaf; but as they grow older, the awareness of death and decay begins to impinge on their consciousness and subtly erode their joie de vivre (a keen enjoyment of living), their idealism - and their assumption of immortality.
As a child matures, he sees death and pain everywhere about him, and begins to lose faith in the ultimate goodness of man. But if he’s reasonably strong - and lucky - he can emerge from this twilight of the soul into a rebirth of life’s élan (enthusiastic and assured vigour and liveliness).
Both because of and in spite of his awareness of the meaninglessness of life, he can forge a fresh sense of purpose and affirmation. He may not recapture the same pure sense of wonder he was born with, but he can shape something far more enduring and sustaining.
The most terrifying fact about the universe is not that it is hostile but that it is indifferent; but if we can come to terms with this indifference and accept the challenges of life within the boundaries of death - however mutable man may be able to make them - our existence as a species can have genuine meaning and fulfilment. However vast the darkness, we must supply our own light.
— Stanley Kubrick in interview for Playboy, Stanley Kubrick Interviews, University Press of Mississippi, 2001, p.73
I can relate to Kubrick's response. Particularly the bit at the end about the "most terrifying fact about the universe is...that it is indifferent." But the indifference of the universe makes the ability of humanity (and other animals?) to feel (and act upon) compassion all the more precious. In that fact, I find my hope.
