Science is one thing, wisdom is another. Science is an edged tool, with which men play like children, and cut their own fingers. If you look at the results which science has brought in its train, you will find them to consist almost wholly in elements of mischief. See how much belongs to the word "Explosion" alone, of which the ancients knew nothing.

Whatever else there may be in our nature, responsibility toward truth is one of its attributes.

In the most modern theories of physics probability seems to have replaced aether as "the nominative of the verb 'to undulate'."

What is possible in the Cavendish Laboratory may not be too difficult in the sun.

We are bits of stellar matter that got cold by accident, bits of a star gone wrong.

Observation and theory get on best when they are mixed together, both helping one another in the pursuit of truth. It is a good rule not to put overmuch confidence in a theory until it has been confirmed by observation. I hope I shall not shock the experimental physicists too much if I add that it is also a good rule not to put overmuch confidence in the observational results that are put forward until they have been confirmed by theory.

Oh leave the Wise our measures to collate. One thing at least is certain, light has weight. One thing is certain and the rest debate. Light rays, when near the Sun, do not go straight.
