It is no accident that the Victorian age, the heyday of conventionalism, was the cultural bloom of economic liberalism.

It may be that just as tonality recurs in music and realism in painting, so the idea of liberalism recurs in politics-though each time in a different vein.

A Liberal is a man who uses his legs and his hands at the behest-at the command-of his head.

The essence of the Liberal outlook lies not in what opinions are held, but in how they are held: instead of being held dogmatically, they are held tentatively, and with a consciousness that new evidence may at any moment lead to their abandonment.
