Philosophers, for the most part, are constitutionally timid, and dislike the unexpected. Few of them would be genuinely happy as pirates or burglars. Accordingly they invent systems which make the future calculable, at least in its main outlines. – Bertrand Russell
My definition [of a philosopher] is of a man up in a balloon, with his family and friends holding the ropes which confine him to earth and trying to haul him down. – Louisa May Alcott, in Life, Letters, and Journals, ed. E.D. Cheney, 1889
