The idea of history in any age, like the idea of property, or of progress, is an unstable compound; it is put together as needed, by historians or by philosophers, out of the irreconcilable opinions of men. – F. Smith Fussner, The Historical Revolution
Every science has for its basis a system of principles as fixed and unalterable as those by which the universe is regulated and governed. Man cannot make principles he can only discover them. – Thomas Paine
