Frege on truth, beauty and goodness

The paper attempts to shed light on Frege's views on the relation of logic to truth by looking at several passages in which he compares it to the relation of ethics to the good and aesthetics to the beautiful. It turns out that Frege makes four distinct points by means of these comparisons only one of which both concerns truth and makes use of distinctive features of ethics and aesthetics. This point is that logic is about reaching truth in the way that ethics is about reaching the good and aesthetics the beautiful. I then sketch how Frege can plausibly maintain this view about logic. (A more detailed version of Frege's positive view is given in my unpublished "Frege on the Relations Between Logic and Thought.")
