Personally, People Know Themselves Very Poorly.

The Presentations And Conceptions Of The Average Man Of The World Are Formed And Dominated, Not By The Full And Pure Desire For Knowledge As An End In Itself, But By The Struggle To Adapt Himself Favourably To The Conditions Of Life.

Man Is Pre-eminently Endowed With The Power Of Voluntarily And Consciously Determining His Own Point Of View.

The History Of The Development Of Mechanics Is Quite Indispensable To A Full Comprehension Of The Science In Its Present Condition. It Also Affords A Simple And Instructive Example Or The Processes By Which Natural Science Generally Is Developed.

Not Bodies Produce Sensations, But Element-complexes (sensation-complexes) Constitute The Bodies. When The Physicist Considers The Bodies As The Permanent Reality, The 'elements' As The Transient Appearance, He Does Not Realise That All 'bodies' Are Only Mental Symbols For Element-complexes (sensation-complexes).

Science Itself, Therefore, May Be Regarded As A Minimal Problem, Consisting Of The Completest Possible Presentment Of Facts With The Least Possible Expenditure Of Thought.
