The field of consciousness is tiny. It accepts only one problem at a time.

When we think that the machine will harm man, then it is perhaps because we are not yet capable of judging the rapid changes it has brought about. We hardly feel at home in this landscape of mines and power stations. We have just moved into this new home that we have not even finished yet. Everything around us has changed so fast - personal relations, working conditions, habits. Even our state of mind is in turmoil.

The friend within the man is that part of him which belongs to you and opens to you a door which never, perhaps, is opened to another. Such a friend is true, and all he says is true; and he loves you even if he hates you in other mansions of his heart.

One only really sees with the heart.

A civilization is built on what is required of men, not on that which is provided for them.

Grown-ups love figures... When you tell them you've made a new friend they never ask you any questions about essential matters. They never say to you "What does his voice sound like? What games does he love best? Does he collect butterflies? " Instead they demand "How old is he? How much does he weigh? How much money does his father make? " Only from these figures do they think they have learned anything about him.

If a composer suffers from loss of sleep and his sleeplessness induces him to turn out masterpieces, what a profitable loss it is!
