Optimism is the staunchest worshipper of life.

I am convinced that an electronic machine, no matter how smart and intelligent, being still a mere spatial structure in concept, can neither innovate nor even understand the self-evident proposition: 'No spatial structure can be a representation of any feeling'. Such innovation can only be a work of a non-spatial mind, like a human being, and only such innovation, it should be acknowledged, can pave the way for further scientific achievements.

The history of science is the saga of nature defying common sense.

He is man whose heart is spirited and eyes are wet each moment on account of the sorrow, compassion, virtue, beauty, and nobility that decorate this world.

The world is a garden of philosophy. God is its gardener; Man is the visitor. And any tree that does not bear fruits of philosophy either does not belong to that garden or is yet to be grown.

The only absurdity in which I find equally immense compassion and morality is Christianity - though the compassion is outlandish and the morality is blemished.

Pain is a poison; pleasure an intoxicant.
