The Sentimentalist, roughly speaking, is the man who wants to eat his cake and have it. He has no sense of honor about ideas; he will not see that one must pay for an idea as well as for anything else.

All things are from God; and above all, reason and imagination and the great gifts of the mind. They are good in themselves; and we must not altogether forget their origin even in their perversion.
