Knowledge and action... are only two aspects of one and the same faculty... There are things that intelligence alone is able to seek, but which, by itself, it will never find. These things instinct alone could find; but it will never seek them.
You would hardly appreciate the comic if you felt yourself isolated from others. Laughter appears to stand in need of an echo. Listen to it carefully: it is not an articulate, clear, well-defined sound; it is something which would fain be prolonged by reverberating from one to another, something beginning with a crash, to continue in successive rumblings, like thunder in a mountain. still, this reverberation cannot go on for ever. It can travel within as wide a circle as you please: the circle remains, none the less, a closed one.
Life is something you measure not in years but in precious moments - and in how you value those moments. The responsibility for making such moments meaningful is yours alone. There are no definitions of failure or success except the ones you specify for yourself. You are the meaning of your own life.
In every community there is a class of people profoundly dangerous to the rest. I don't mean the criminals. For them we have punitive sanctions. I mean the leaders. Invariably the most dangerous people seek the power. While in the parlors of indignation the right-thinking citizen brings his heart to a boil. In here, the human bosom -- mine, yours, everybody's -- there isn't just one soul. There's a lot of souls. But there are two main ones, the real soul and a pretender soul. Now! Every man realizes that he has to love something or somebody. He feels that he must go outward. 'If thou canst not love, what art thou?' Are you with me?
Instinct gave place temporarily to a system of habits, each one of which became contingent, their convergence of which became contingent, their convergence towards the preservation of society being alone necessary, and this necessity bringing back instinct with it. The necessity of the whole, felt behind the contingency of the parts, is what we call moral obligation in general - it being understood that the parts are contingent in the eyes of society only; to the individual, into whom society inculcates its habits, the part is as necessary as the whole.
When you have overcome one temptation, you must be ready to enter the lists with another. As distrust, in some sense, is the mother of safety, so security is the gate of danger. A man had need to fear this most of all, that he fears not at all.
Some there are who are clear-sighted and do not need my teachings, and some whose eyes are clouded with dust who will not heed it though given, but between these two there are also some with but little dust in their eyes, who can be helped to see; and for the sake of these I will go back among mankind and teach.
