Truth is the offspring of silence and meditation.

Is not Fire a Body heated so hot as to emit Light copiously? For what else is a red hot Iron than Fire? And what else is a burning Coal than red hot Wood?

Every body persists in a state of rest or of uniform motion in a straight line, unless it is compelled to change that state by forces having impact upon it.

Truth is the offspring of silence and meditation.

The Ignis Fatuus is a vapor shining without heat.

If I have done the public any service, it is due to my patient thought.

What goes up must come down.
