The typical intellectual believes everything must be explainable, while the scientist knows that a great many things are not, in our present state of knowledge. The good scientist is essentially a humble person. But you already have the great difference in that respect between, say, the scientist and the engineer. The engineer is the typical rationalist, and he dislikes any- thing which he cannot explain and which he can’t see how it works. What I now call constructivism I used to call the engineering attitude of mind, because the word is very frequently used. They want to direct the economy as an engineer directs an enterprise. The whole idea of planning is essentially an engineering approach to the economic world.
