My Fundamental Axiom Of Speculative Philosophy Is

It Is Wrong For A Man To Say That He Is Certain Of The Objective Truth Of Any Proposition Unless He Can Produce Evidence Which Logically Justifies That Certainty.

In Matters Of The Intellect, Do Not Pretend That Conclusions Are Certain Which Are Not Demonstrated Or Demonstrable. That I Take To Be The Agnostic Faith, Which If A Man Keep Whole And Undefiled, He Shall Not Be Ashamed To Look The Universe In The Face, Whatever The Future May Have In Store For Him.

Time, Whose Tooth Gnaws Away Everything Else, Is Powerless Against Truth.

People Never Will Recollect That Mere Learning And Mere Cleverness Are Of Next To No Value In Life, While Energy And Intellectual Grip, The Things That Are Inborn And Cannot Be Taught, Are Everything.

Every Philosophical Thinker Hails It [the Origin Of Species] As A Veritable Whitworth Gun In The Armoury Of Liberalism.
