What the sorrowful Jew of Amsterdam called the essence of a thing, the effort that it makes to persist indefinitely in its own being, self-love, the longing for immortality, is it not perhaps the primal and fundamental condition of all reflective or human knowledge? And is it not therefore the true base, the real starting-point, of all philosophy, although the philosophers, perverted by intellectualism, do not recognize it?

The truth is sum, ergo cogito - I am, therefore I think, although not everything that is thinks. Is not consciousness of thinking above all consciousness of being? Is pure thought possible, without consciousness of self, without personality? Can there exist pure knowledge without feeling, without that species of materiality which feelings lends to it? Do we not perhaps feel thought, and do we not feel ourselves in the act of knowing and willing? Could not the man in the stove [Descartes] have said: "I feel, therefore I am"? or "I will, therefore I am"? And to feel oneself, is it not perhaps to feel oneself imperishable?

And he arrives at the cogito ergo sum, which St. Augustine had already anticipated... "I think therefore I am," can only mean "I think, therefore I am a thinker"; this being of "I am," which is deduced from "I think," is merely a knowing; this being is a knowledge, but not life. And the primary reality is not that I think, but that I live, for those also live who do not think. Although this living may not be a real living. God! what contradictions when we seek to join in wedlock life and reason!

Yes perhaps, as the Sage says, "nothing worthy of proving can be proven, nor yet disproven"; but can we restrain that instinct which urges man to wish to know, and above all to wish to know the things which conduce to life, to eternal life? Eternal life, not eternal knowledge as the Alexandrian gnostic said. For living is one thing and knowing is another; and... perhaps there is an opposition between the two that we may say that everything vital is anti-rational, not merely irrational, and that everything rational is anti-vital. And this is the basis of the tragic sense of life.

Reason, that which we call reason, reflex and reflective knowledge, the distinguishing mark of man, is a social product.

Knowledge is employed in the service of the necessity of life and primarily in the service of the instinct of personal preservation. The necessity and this instinct have created in man the organs of knowledge and given them such capacity as they possess. Man sees, hears, touches, tastes and smells that which it is necessary for him to see, hear, touch, taste and smell in order to preserve his life. The decay or loss of any of these senses increases the risks with which his life is environed, and if it increases them less in the state of society in which we are actually living, the reason is that some see, hear, touch, taste and smell for others. A blind man, by himself and without a guide, could not live long. Society is an additional sense; it is the true common sense.

Apart from the fact there is no normal standard of health, nobody has proved that man is necessarily cheerful by nature. And further, man, by the very fact of being man, of possessing consciousness, is, in comparison with the ass or the crab, a diseased animal. Consciousness is a disease.

Hegel made famous his aphorism that all the rational is real and all the real rational; but there are many of us who, unconvinced by Hegel, continue to believe that the real, the really real, is irrational, that reason builds upon irrationalities. Hegel, a great framer of definitions, attempted with definitions to reconstruct the universe, like that artillery sergeant who said that cannon were made by taking a hole and enclosing it with steel.

Man is said to be a reasoning animal. I do not know why he has not been defined as an affective or feeling animal. Perhaps that which differentiates him from other animals is feeling rather than reason. More often I have seen a cat reason than laugh or weep. Perhaps it weeps or laughs inwardly - but then perhaps, also inwardly, the crab resolves equations of the second degree.

Little can be hoped for from a ruler... who has not at some time or other been preoccupied, even if only confusedly, with the first beginning and ultimate end of all things, and above all of man, with the "why" of his origin and the "wherefore" of his destiny.
