　　The instinctive foundation of the intellectual life is curiosity, which is found among animals in its elementary form. Intelligence demands an alert curiosity, but it must be of a certain kind. The sort that leads village neighbors to try to peer through curtains after dark has not very high value.The widespread interest in gossip is inspired,, not by love of knowledge, but by malice (恶意) ;no one gossips about other people's secret virtues, but only about their secret vices. Curiosity properly so-called, on the other hand, is inspired by a genuine love of knowledge. You may see this impulse, in a moderately pure form, at work in a cat that has been brought to a strange room and proceeds to smell every comer and every piece of furniture. You will see it also in children who are passionately interested when a drawer or cupboard, usually closed, is open for their inspection. Animals, machines, thunderstorms, and all forms of manual work arouse the curiosity of children, whose thirst for knowledge puts the most intelligent adult to shame. This impulse grows weaker with-advancing years until at last what is unfamiliar inspires only disgust, with no desire for a closer acquaintance.
　　This is the stage at which people announce that "things are not what they were in my young days". The thing that is not the same as it was in that far-off time is the speaker's curiosity. And with the death of curiosity, we may reckon that active intelligence,also, has died. But although curiosity lessens in intensity and in extent after childhood, it may for a long time improve in quality. Curiosity about general propositions shows a higher level of intelligence than does curiosity about particular facts. Broadly speaking, the higher the order of generality, the greater is the intelligence involved. Curiosity dissociated from personal advantage shows a higher development than does curiosity connected, say, with a chance of food. The cat that sniffs in a new room is not a wholly disinterested scientific inquirer but probably also wants to find out whether there are mice about. Perhaps it is not quite correct to say that curiosity is best when it is disinterested but rather that it is best when the connection with other interests is not direct and obvious, but discoverable only by means of a certain degree of intelligence.
According to the passage, how may most intelligent adult feel facing children's thirst for knowledge?
