3～5

3.Perhaps the most obvious way in which birds differ from men in their behaviour is that they can do all that they have to do, including some quite complicated things, without ever being taught. Flying, to start with, is an activity which, for all its astonishing complexity of balance and aeronautical adjustment, comes untaught to birds. Young birds very frequently make their first flight when their parents are out of sight. Practice of course makes perfect and puts a polish on the somewhat awkward first performance; but there is no elaborate learning needed as with our learning of golf or tennis or figure skating.
4.That all men are equal is an assertion to which, at ordinary times, no sane human being has ever given assent. A man who has to undergo a dangerous operation does not act on the supposition that one doctor is just as good as another. And when they require Civil Servants, even the most democratic governments take a careful selection among their theoretically equal subjects. At ordinary times, then, we are perfectly certain that men are not equal. But when, in a democratic country, we think or act politically we are no less certain that men are equal.
5.Foolishly arrogant as I was, I used to judge the worth of a person by the intellectual power and attainment. I could see no good where there was no logic, no charm where there was no learning. Now I think that one has to distinguish between two forms of intelligence, that of the brain, and that of the heart, and I have come to regard the second by far the more important.
