While we ourselves are the living graves of murdered beasts, how can we expect any ideal conditions on this earth? - George Bernard Shaw

This is the true joy in life, the being used for a purpose recognized by yourself as a mighty one; the being thoroughly worn out before you are thrown on the scrap heap; the being a force of Nature instead of a feverish selfish little clod of ailments and grievances complaining that the world will not devote itself to making you happy.

Progress is impossible without change; and those who cannot change their minds cannot change anything. Creeds, articles, and institutes of religious faith ossify our brains and make change impossible. As such they are nuisances, and in practice have to be mostly ignored.

"There's only one way of escaping trouble; and that's killing things." Henry Higgins, Act V, Pygmalion
