You are not listening to me. You are making phrases about Byron. And while you gesticulate, with your cloak, your cane, I am trying to expose a secret told to nobody yet; I am asking you (as I stand with my back to you) to take my life in your hands and tell me whether I am doomed always to cause repulsion in those I love?virginia woolf

Minds vary in sensitiveness and in self-power, as bodies do in susceptibility of attraction and repulsion. When, when shall we learn that they are governed by laws as inexorable as physical laws, and that a man can as easily refuse to obey what has power over him as a steel atom can resist the magnet?james anthony froude
It seems safe to look forward to the time when the conception of attractive and repulsive forces, having served its purpose as a useful piece of scientific scaffolding, will be replaced by the deduction of the phenomena known as attraction and repulsion, from the general laws of motion.thomas henry huxley
