The intelligent person is not one who merely knows what is good and what is bad. The intelligent person is one who, when he sees what is good, follows it, and when he sees evil, shuns it.
Without going out-of-doors, one can know all he needs to know. Without even looking out of his window, one can grasp the nature of everything. Without going beyond his own nature, one can achieve ultimate wisdom. Therefore, the intelligent man knows all he needs to know without going away, And sees all he needs to see without looking elsewhere, And does all he needs to do wihout undue exertion.
There are three kinds of intelligence: one kind understands things for itself, the other appreciates what others can understand, the third understands neither for itself nor through others. This first kind is excellent, the second good, and the third kind useless.
For me, consciousness is the most interesting unsolved problem of science, and, in fact, we may never know what it is about a particular arrangement of neurons that gives rise to consciousness. Our consciousness, like the air we breathe or like the passage of time, is central to our existence as intelligent beings.
And therefore only the enlightened sovereign and the worthy general who are able to use the most intelligent people as agents are certain to achieve great things.
He with whom neither slander that gradually soaks into the mind, nor statements that startle like a wound in the flesh, are successful may be called intelligent indeed.
It is a sign of our times, conspicuous to the coarsest observer, that many intelligent and religious persons withdraw themselves from the common labors and competitions of the market and the caucus, and betake themselves to a certain solitary and critical way of living, from which no solid fruit has yet appeared to justify their separation.
Every intelligent individual wants to know what makes him tick, and yet is at once fascinated and frustrated by the fact that oneself is the most difficult of all things to know.
Nature shows that with the growth of intelligence comes increased capacity for pain, and it is only with the highest degree of intelligence that suffering reaches its supreme point.
Oh, gentlemen, perhaps I really regard myself as an intelligent man only because throughout my entire life I've never been able to start or finish anything. Granted, granted I'm a babbler, a harmless, irksome babbler, as we all are. But what's to be done if the sole and express purpose of every intelligent man is babble--that is, a deliberate pouring from empty into void.
I came to realize that I was always looking for myself in the women I loved. I looked at their lovely, clean faces, and saw myself reflected in them. They, on the other hand, looked at me and saw the dirt on my face and, however intelligent and self confident they were, they ended up seeing themselves reflected in me and thinking that they were worse than they were. Please don't let that happen to you.
