It seems to be the special peculiarity of human beings that they reflect: they think about thinking and know that they know. This, like other feedback systems, may lead to vicious circles and confusions if improperly managed, but self-awareness makes human experience resonant. It imparts that simultaneous "echo" to all that we think and feel as the box of a violin reverberates with the sound of the strings. It gives depth and volume to what would otherwise be shallow and flat.
The police have enough work to keep them busy regulating automobile traffic, preventing robberies and crimes of violence and helping lost children and little old ladies find their way home. As long as the police confine themselves to such activities they are respected friends of the public. But as soon as they begin inquiring into people's private morals, they become nothing more than armed clergymen.
Life exists only at this very moment, and in this moment it is infinite and eternal, for the present moment is infinitely small; before we can measure it, it has gone, and yet it exists forever.
Philosophers, for example, often fail to recognize that their remarks about the universe apply also to themselves and their remarks. If the universe is meaningless, so is the statement that it is so.
We are seeing, then, that our experience is altogether momentary. From one point of view, each moment is so elusive and so brief that we cannot even think about it before it has gone. From another point of view, this moment is always here, since we know no other moment than the present moment. It is always dying, always becoming past more rapidly than imagination can conceive. Yet at the same time it is always being born, always new, emerging just as rapidly from that complete unknown we call the future. Thinking about it almost makes you breathless.
Irrevocable commitment to any religion is not only intellectual suicide; it is positive unfaith because it closes the mind to any new vision of the world. Faith is, above all, openness - an act of trust in the unknown.
Now, you see, if you understand what I'm saying, with your intelligence, and then take the next step and say "But I understood it now, but I didn't feel it." Then, next I raise the question: Why do you want to feel it? You say: "I want something more", because that's again that spiritual greed. And you could only say that because you didn't understand it.
We are all as much extraordinary phenomena of nature as trees, clouds, the patterns in running water, the flickering of fire, the arrangement of the stars and the form of a galaxy.
