It Is What We Know

True Science Teaches Us To Doubt And, In Ignorance, To Refrain.

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 Terrain Is Everything; The Germ Is Nothing.

Our Ideas Are Only Intellectual Instruments Which We Use To Break Into Phenomena; We Must Change Them When They Have Served Their Purpose, As We Change A Blunt Lancet That We Have Used Long Enough.
