The Fundamental Thing About Human

[great Scientists] Are Men Of Bold Ideas, But Highly Critical Of Their Own Ideas: They Try To Find Whether Their Ideas Are Right By Trying First To Find Whether They Are Not Perhaps Wrong. They Work With Bold Conjectures And Severe Attempts At Refuting Their Own Conjectures.

Bold Ideas, Unjustified Anticipations, And Speculative Thought, Are Our Only Means For Interpreting Nature: Our Only Organon, Our Only Instrument, For Grasping Her. And We Must Hazard Them To Win Our Prize. Those Among Us Who Are Unwilling To Expose Their Ideas To The Hazard Of Refutation Do Not Take Part In The Scientific Game.

We Hate The Very Idea That Our Own Ideas May Be Mistaken, So We Cling Dogmatically To Our Conjectures.
