If you want to know the taste of a pear, you must change the pear by eating it yourself. If you want to know the theory and methods of revolution, you must take part in revolution. All genuine knowledge originates in direct experience.
If you wish to know how much preferable wisdom is to gold, then observe: if you change gold you get silver for it, but your gold is gone; but if you exchange one sort of wisdom for another, you obtain fresh knowledge, and at the same time keep what you possessed before.
In any society, the artist has a responsibility. His effectiveness is certainly limited and a painter or writer cannot change the world. But they can keep an essential margin of non-conformity alive. Thanks to them the powerful can never affirm that everyone agrees with their acts. That small difference is important.
In human life, art may arise from almost any activity, and once it does so, it is launched on a long road of exploration, invention, freedom to the limits of extravagance, interference to the point of frustration, finally discipline, controlling constant change and growth.
It is always a great honour to mention a truth which has not become widespread yet. One of these truths is that man has no soul; he has only 'body' and 'mind'. Man's unshakable belief on the soul will not change this scientific truth! No belief can be higher than the scientific truths! Man can be born, can walk and work and can think without owning a mysterious and an immaterial soul! The soullessness of the man is a great tragedy both for the man and for the religion. But Man, contrary to the religion, will come out with triumph from this tragedy.
It is by a wise economy of nature that those who suffer without change, and whom no one can help, become uninteresting. Yet so it may happen that those who need sympathy the most often attract it the least.
It is change, continuing change, inevitable change, that is the dominant factor in society today. No sensible decision can be made any longer without taking into account not only the world as it is, but the world as it will be. This, in turn, means that our statesmen, our businessmen, our every man must take on a science fictional way of thinking.
It is difficult for intellect, technology, and peace to coexist. Not because peace is static where the other two require constant stimulation. Peace can embrace change. It is because we live in a world where intellect and technology compete for power. And peace does not allow for inequality or competition.
