In the first place a philosophical proposition must be general. It must not deal specially with things on the surface of the earth, or within the solar system, or with any other portion of space and time.... This brings us to a second characteristic of philosophical propositions, namely that they must be a priori. A philosophical proposition must be such as can neither be proved nor disproved by empirical evidence.... Philosophy, if what has been said is correct, becomes indistinguishable from logic as that word has now come to be used.

It is obvious that truth in general depends on both language and extra-linguistic fact. The statement 'Brutus killed Caesar' would be false if the world had been different in certain ways, but it would also be false if the word 'killed' happened rather to have the sense of 'begat'. Thus one is tempted to suppose in general that the truth of a statement is somehow analysable into a linguistic component and a factual component. Given this supposition it next seems reasonable that in some statements the factual component should be null and that these are the analytic statements. But for all its a priori reasonableness, a boundary between the analytic and synthetic statements simply has not been drawn. That there is such a distinction to be drawn at all is an unempirical dogma of empiricists, a metaphysical article of faith.

This is to prevent him from having 1. the sense of romantic solitude (if he is worth anything he will develop a proper and useful solitude) which identification with the hero gives. 2. cant ideas of right and wrong, absurd systems of honor and morality which never will he be able completely to get rid of, 3. the attainment of ''ideals',' of a priori desires, of a priori emotions. He should amuse himself with fact only he will then not learn that if the weak younger son do or do not the magical honorable thing he will win the princess with hair like flax.
