Abstract
Like others who work in philosophy, I asked myself from time to time what I was trying to do in my philosophizing. The natural answer seemed to be that I was trying to understand the world, and to do so by taking any thing or event that puzzled me and pressing the question Why? till I arrived at the understanding I sought. And what does understanding anything mean? It means to explain it or to render it intelligible. And when does it become intelligible? Only when it is seen in context, and seen as required by that context. This requirement is of various kinds. Sometimes it is causal, as when an attack of malaria is explained by the bite of the anopheles mosquito. Sometimes it is a means-end relation, as when the presence of a rudder is explained as a means of guiding a ship. Sometimes it is logical, as when the Pythagorean theorem is explained by showing that it follows necessarily from other accepted propositions of geometry.
