Algebra is the metaphysics of arithmetic.
Beauty is power; a smile is its sword.
Diseases are the tax on pleasures.
Even if you are on the right track, you will get run over if you just sit there.
Good words cool more than cold water.
In a thousand pounds of law there is not an ounce of love.
Industry is fortune's right hand, and frugality its left.
Never meet trouble half-way.
Nothing is invented and perfected at the same time.
