To have intelligence there must be freedom, and you cannot be free if you are constantly being urged to become like some hero, for then the hero is important and not you.
One of the great problems of philosophy is the relationship between the realm of knowledge and the realm of values. Knowledge is what is; values are what ought to be.
Biology occupies a position among the sciences at once marginal and central. Marginal because -- the living world constituting but a tiny and very "special" part of the universe -- it does not seem likely that the study of living beings will ever uncover general laws applicable outside the biosphere. But if the ultimate aim of the whole of science is indeed, as I believe, to clarify man's relationship to the universe, then biology must be accorded a central position.
All of that is constantly operating when you not only learn, but when you recall. But as you recall in a different light, the weights with which something is more probably going to be or not recalled on the next instance, are going to be changed. So you're constantly changing the way, for instance, synapses are going to fire very easily or not so easily.
To put it bluntly but fairly, anyone today who doubts that the variety of life on this planet was produced by a process of evolution is simply ignorant—inexcusably ignorant, in a world where three out of four people have learned to read and write.
When you call yourself an Indian or a Muslim or a Christian or a European, or anything else, you are being violent. Do you see why it is violent? Because you are separating yourself from the rest of mankind. When you separate yourself by belief, by nationality, by tradition, it breeds violence. So a man who is seeking to understand violence does not belong to any country, to any religion, to any political party or partial system; he is concerned with the total understanding of mankind.
Courage is worthy of respect when displayed in the maintenance of legitimate claims and in the repelling of aggressions, bodily or other. Courage is worthy of yet higher respect when danger is faced in defence of claims common to self and others, as in resistance to invasion. Courage is worthy of the highest respect when risk to life or limb is dared in defence of others.
