The foolish man wonders at the unusual, but the wise man at the usual.

Happy is he who looks only into his work to know if it will succeed, never into the times or the public opinion; and who writes from the love of imparting certain thoughts and not from the necessity of sale - who writes always to the unknown friend.

There will always be in society certain persons who are mercuries of its approbation, and whose glance will at any time determinefor the curious their standing in the world. These are the chamberlains of the lesser gods. Accept their coldness as an omen of grace with the loftier deities, and allow them all their privilege.

The lessons of science should be experimental also. The sight of a planet through a telescope is worth all the course on astronomy; the shock of the electric spark in the elbow outvalues all theories; the taste of the nitrous oxide, the firing of an artificial volcano, are better than volumes of chemistry.

What forests of laurel we bring, and the tears of mankind, to those who stood firm against the opinion of their contemporaries!

The secret of success in society is a certain heartiness and sympathy.

Indeed the river is a perpetual gala, and boasts each month a new ornament.
