Feeling Alone Guides The Mind.

As Soon As The Circumstances Of An Experiment Are Well Known, We Stop Gathering Statistics. ... The Effect Will Occur Always Without Exception, Because The Cause Of The Phenomena Is Accurately Defined. Only When A Phenomenon Includes Conditions As Yet Undefined,only When A Phenomenon Includes Conditions As Yet Undefined, Can We Compile Statistics. ... We Must Learn Therefore That We Compile Statistics Only When We Cannot Possibly Help It; For In My Opinion, Statistics Can Never Yield Scientific Truth.

The Great Experimental Principle, Then, Is Doubt, That Philosophic Doubt Which Leaves To The Mind Its Freedom And Initiative, And From Which The Virtues Most Valuable To Investigators In Physiology And Medicine Are Derived.

A Man Of Science Rises Ever, In Seeking Truth; And If He Never Finds It In Its Wholeness, He Discovers Nevertheless Very Significant Fragments; And These Fragments Of Universal Truth Are Precisely What Constitutes Science.

It Has Often Been Said That, To Make Discoveries, One Must Be Ignorant. This Opinion, Mistaken In Itself, Nevertheless Conceals A Truth. It Means That It Is Better To Know Nothing Than To Keep In Mind Fixed Ideas Based On Theories Whose Confirmation We Constantly Seek, Neglecting Meanwhile Everything That Fails To Agree With Them.

The Doubter Is A True Man Of Science: He Doubts Only Himself And His Interpretations, But He Believes In Science.
