Knowledge is not eating, and we cannot expect to devour and possess what we mean. Knowledge is recognition of something absent; it is a salutation, not an embrace.

Man alone knows that he must die; but that very knowledge raises him, in a sense, above mortality, by making him a sharer in the vision of eternal truth. He becomes the spectator of his own tragedy; he sympathizes so much with the fury of the storm that he has no ears left for the shipwrecked sailor, though the sailor were his own soul. The truth is cruel, but it can be loved, and it makes free those who have loved it.

We need sometimes to escape into open solitudes, into aimlessness, into the moral holiday of running some pure hazard in order to sharpen the edge of life, to taste hardship, and to be compelled to work desperately for a moment at no matter what.

You cannot prove realism to a complete sceptic or idealist; but you can show an honest man that he is not a complete sceptic or idealist, but a realist at heart. So long as he is alive his sincere philosophy must fulfil the assumptions of his life and not destroy him.
