I Believe That The More Thoroughly Science

Heavier-than-air Flying Machines Are Impossible.

We All Confidently Believe That There Are At Present, And Have Been From Time Immemorial, Many Worlds Of Life Besides Our Own. . . . [this] May Seem Wild, And Visionary; All I Maintain Is That It Is Not Unscientific.

If You Cannot Measure It, Then It Is Not Science.

There Is Nothing In Science Which Teaches The Origin Of Anything At All.

Mathematics Is The Only True Metaphysics.
