— Dave Galanter"A choice is the root of all morality. Without choice, one can have no moral code. In a vacuum bereft of alternatives, there can be no values. And without values, there can be no reason for a code of ethics. What gives our lives meaning is which alternatives we choose. If we have no options, if we can take but one path, we are by definition slaves."

The twentieth century had dispensed with the formal declaration of war and introduced the fifth column, sabotage, cold war, and war by proxy, but that was only the begining. Summit meetings for disarmament pursued mutual understanding and a balance of power but were also held to learn the strengths and weaknesses of the enemy. The world of the war-or-peace alternative became a world in which war was peace and peace war.

. . . the membership relation for sets can often be replaced by the composition operation for functions. This leads to an alternative foundation for Mathematics upon categories -- specifically, on the category of all functions. Now much of Mathematics is dynamic, in that it deals with morphisms of an object into another object of the same kind. Such morphisms (like functions) form categories, and so the approach via categories fits well with the objective of organizing and understanding Mathematics. That, in truth, should be the goal of a proper philosophy of Mathematics.
