It is my aim in this paper to take an especially broad look at the logic of Boole. This does not mean that I think details are not important, but the more you go into them the more you get caught at a particular spot in space and time—say Lincoln in the year 1847—and Boole seems correspondingly further away from us. If the details of Boole's logic are left aside, what remains is a science. The question therefore arises of how much Boole's concept of a science determined his logic. This is the vital question of the following exposition.
