Science means simply the aggregate of all the recipes that are always successful. All the rest is literature.

History is the science of things which are not repeated.

That which has been believed by everyone, always and everywhere, has every chance of being false.

In science, address the few, in literature, the many. In science, the few must dictate opinion to the many; in literature, the many, sooner or later, force their judgment on the few.

In science read the newest works, in literature read the oldest.

At times I think and at times I am.
