Every New Concept First Comes

It Is Important To Understand What I Mean By Semiosis. All Dynamic Action, Or Action Of Brute Force, Physical Or Psychical, Either Takes Place Between Two Subjects, Whether They React Equally Upon Each Other, Or One Is Agent And The Other Patient, Entirely Or Partially, Or At Any Rate Is A Resultant Of Such Actions Between Pairs. But By "semiosis" I Mean, On The Contrary, An Action, Or Influence, Which Is, Or Involves, A Cooperation Of Three Subjects, Such As A Sign, Its Object, And Its Interpretant, This Tri-relative Influence Not Being In Any Way Resolvable Into Actions Between Pairs.

Mathematics Is Purely Hypothetical: It Produces Nothing But Conditional Propositions.

It Is Not Knowing, But The Love Of Learning, That Characterizes The Scientific Man.

A Hypothesis Is Something Which Looks As If It Might Be True And Were True, And Which Is Capable Of Verification Or Refutation By Comparison With Facts.

A Sign, Or Representamen, Is Something Which Stands To Somebody For Something In Some Respect Or Capacity. It Addresses Somebody,that Is, Creates In The Mind Of That Person An Equivalent Sign, Or Perhaps A More Developed Sign. That Sign Which It Creates I Call The Interpretant Of The First Sign. The Sign Stands For Something, Its Object. It Stands For That Object, Not In All Respects, But In Reference To A Sort Of Idea, Which I Have Sometimes Called The Ground Of The Representamen.
