Philosophy
"It has often been held that ethical statements cannot follow from premises consisting exclusively of statements of fact. Thus Karl Popper
once said: 'Perhaps the simplest and most important point about ethics is purely logical. I mean the impossibility to derive [sic] nontautological ethical rules-imperatives; principles of policy; aims; or however we may describe them-from statements of facts.
Only if this fundamental logical position is realized can we begin to formulate the real problems of moral philosophy, and to appreciate their difficulty.'"
