Who peppered the highest was surest to please. - Oliver Goldsmith

Some fleeting good, that mocks me with the view.

The canvas glow'd beyond ev'n Nature warm,
The pregnant quarry teem'd with human form.

Men may be very learned, and yet very miserable; it is easy to be a deep geometrician, or a sublime astronomer, but very difficult to be a good man. I esteem, therefore, the traveller who instructs the heart, but despise him who only indulges the imagination. A man who leaves home to mend himself and others, is a philosopher; but he who goes from country to country, guided by the blind impulse of curiosity, is only a vagabond.
