The similarity between Christ and Socrates consists essentially in their dissimilarity. Just as philosophy begins with doubt, so also a life that may… - Søren Kierkegaard

It is as useless for a person to want first of all to decide the externals and after that the fundamentals as it is for a cosmic body, thinking to form itself, first of all to decide the nature of its surface, to what bodies it should turn its light, which its dark side, without first letting the harmony of centrifugal and centripetal forces realize its existence and letting the rest come of itself. One must learn to know oneself before knowing anything else (gnothi seauton). Not until a person has inwardly understood himself and then sees the course he is to take does his life gain peace and meaning.

Do you not know that there comes a midnight hour when every one has to throw off his mask? Do you believe that life will always let itself be mocked? Do you think you can slip away a little before midnight in order to avoid this? Or are you not terrified by it? I have seen men in real life who so long deceived others that at last their true nature could not reveal itself;... In every man there is something which to a certain degree prevents him from becoming perfectly transparent to himself; and this may be the case in so high a degree, he may be so inexplicably woven into relationships of life which extend far beyond himself that he almost cannot reveal himself. But he who cannot reveal himself cannot love, and he who cannot love is the most unhappy man of all.

It is perfectly true, as the philosophers say, that life must be understood backwards. But they forget the other proposition, that it must be lived forwards.
