Outside our consciousness there lies the cold and alien world of actual things. Between the two stretches the narrow borderland of the senses. No communication between the two worlds is possible excepting across the narrow strip. For a proper understanding of ourselves and of the world, it is of the highest importance that this borderland should be thoroughly explored.

I grow increasingly aware, and in more ways than expected that I am at the center of my own field; and whether it be folly or wisdom, it is a very pleasant feeling.

The rigour of science requires that we distinguish well the undraped figure of Nature itself from the gay-coloured vesture with which we clothe her at our pleasure.

From the outset Maxwell's theory excelled all others in elegance and in the abundance of the relations between the various phenomena which it included.

Maxwell's theory is Maxwell's system of equations.

I also require much time to ponder over the matters themselves, and particularly the principles of mechanics (as the very words: force, time, space, motion indicate) can occupy one severely enough; likewise, in mathematics, the meaning of imaginary quantities, of the infinitesimally small and infinitely large and similar matters.
