Science Rejects The Indeterminate.

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

Experiment Is Fundamentally Only Induced Observation.

Even Mistaken Hypotheses And Theories Are Of Use In Leading To Discoveries. This Remark Is True In All The Sciences. The Alchemists Founded Chemistry By Pursuing Chimerical Problems And Theories Which Are False. In Physical Science, Which Is More Advanced Than Biology, We Might Still Cite Men Of Science Who Make Great Discoveries By Relying On False Theories.

Those Who Do Not Know The Torment Of The Unknown Cannot Have The Joy Of Discovery.

Priestley [said] That Each Discovery We Make Shows Us Many Others That Should Be Made.
