The pace of science forces the pace of technique. Theoretical physics forces atomic energy on us; the successful production of the fission bomb forces upon us the manufacture of the hydrogen bomb. We do not choose our problems, we do not choose our products; we are pushed, we are forced -- by what? By a system which has no purpose and goal transcending it, and which makes man its appendix.

Paradoxically, the ability to be alone is the condition for the ability to love.

The only way of full knowledge lies in the act of love; this act transcends thought, it transcends words. It is the daring plunge into the experience of union. To love somebody is not just a strong feeling-it is a decision, it is a judgment, it is a promise.

Happiness does not exclude sadness - if a person responds to life, he's sometimes happy and sometimes sad. What matters is he responds.

Just as love for one individual which excludes the love for others is not love, love for one's country which is not part of one's love for humanity is not love, but idolatrous worship.

The criterion of mental health is not one of individual adjustment to a given social order, but a universal one, valid for all men, of giving a satisfactory answer to the problem of human existence.

I have learnt to appreciate the clarity of English language.
