Know Yourself To Improve Yourself.

All Good Intellects Have Repeated, Since Bacon's Time, That There Can Be No Real Knowledge But That Which Is Based On Observed Facts. This Is Incontestable, In Our Present Advanced Stage; But, If We Look Back To The Primitive Stage Of Human Knowledge, We Shall See That It Must Have Been Otherwise Then. If It Is True That Every Theory Must Be Based Upon Observed Facts; It Is Equally True That Facts Can Not Be Observed Without The Guidance Of Some Theory. Without Such Guidance, Our Facts Would Be Desultory And Fruitless; We Could Not Retain Them: For The Most Part We Could Not Even Perceive Them.

Each Department Of Knowledge Passes Through Three Stages. The Theoretic Stage; The Theological Stage And The Metaphysical Or Abstract Stage.

C'este Donc Par L'étude Des Mathématiques, Et Seulement Par Elle, Que L'on Peut Se Faire Une Idée Juste Et Approfondie De Ce Que C'est Qu'une Science.

Every Science Consists In The Coordination Of Facts; If The Different Observations Were Entirely Isolated, There Would Be No Science.

All Good Intellects Have Repeated, Since Bacon's Time, That There Can Be No Real Knowledge But Which Is Based On Observed Facts.
