What Is Mind? No Matter. What Is

To Be Is To Be Perceived (esse Est Percipi)." Or, "if A Tree Falls In The Forest And No One Is There To Hear It, Does It Make A Sound?

The Real Essence, The Internal Qualities, And Constitution Of Even The Meanest Object, Is Hid From Our View; Something There Is Inevery Drop Of Water, Every Grain Of Sand, Which It Is Beyond The Power Of Human Understanding To Fathom Or Comprehend. But It Is Evidentthat We Are Influenced By False Principles To That Degree As To Mistrust Our Senses, And Think We Know Nothing Of Those Things Which We Perfectly Comprehend.

And What Are These Fluxions? The Velocities Of Evanescent Increments. And What Are These Same Evanescent Increments? They Are Neither Finite Quantities, Nor Quantities Infinitely Small, Nor Yet Nothing. May We Not Call Them The Ghosts Of Departed Quantities...?

The Same Principles Which At First View Lead To Skepticism, Pursued To A Certain Point, Bring Men Back To Common Sense.

The Method Of Fluxions Is The General Key By Help Whereof The Modern Mathematicians Unlock The Secrets Of Geometry, And Consequently Of Nature.
