Astronomy to the selfish becomes astrology.

The wheels and springs of man are all set to the hypothesis of the permanence of nature. We are not built like a ship to be tossed, but like a house to stand.

Men who know the same things are not long the best company for each other.

Books are for nothing but to inspire

Never lose an opportunity of seeing anything beautiful, for beauty is God's handwriting.

The men who carry their points do not need to inquire of their constituents what they should say, but are themselves the country which they represent: nowhere are its emotions or opinions so instant and so true as in them; nowhere so pure from a selfish infusion.

Nothing great ever happened without enthusiasm.
