Great minds discuss ideas. Average minds discuss events. Small minds discuss people.
~ Henry Thomas Buckle
The faculty of art is to change events, the faculty of science is to foresee them. The phenomena with which we deal are controlled by art, they are predicted by science.
You can tell the lowest class by their habit of always talking about persons; the next, by the fact that their habit is always to converse about things; the highest, by their preference for the discussion of ideas.
