The human understanding when it has once adopted an opinion (either as being the received opinion or as being agreeable to itself) draws all things else to support and agree with it. And though there be a greater number and weight of instances to be found on the other side, yet these it either neglects and despises, or else by some distinction sets aside and rejects, in order that by this great and pernicious predetermination the authority of its former conclusions may remain inviolate.
The cause and root of nearly all evils in the sciences is this-that while we falsely admire and extol the powers of the human mind we neglect to seek for its true helps.
But by far the greatest obstacle to the progress of science and to the undertaking of new tasks and provinces therein is found in this-that men despair and think things impossible.
I feel that I am much freer if I'm on my own, but I'm sure that there are a lot of painters who would perhaps be even more inventive if they had people round them... I find that if I am on my own I can allow the paint to dictate to me. So the images that I'm putting down on the canvas dictate the thing to me and it gradually builds up and comes along.
