The business of cenoscopy is to build up as well as we can conceptions of the omne of being and of non-being and of its principal parts.

“Philosophy” has 2 principal meanings

1. The cream of the science, – synthetic or positive philosophy
2. Cenoscopy, the study of the experience already acquired.

A continuum is a system of relations determined by a general rule, which by virtue of its perfect generality does not suppose any ultimate units (indeed such a unit would involve a breach of the continuity, because introducing something not general), but which yet not only permits the distinction of units but provides relations by which any multitude of ultimate units would be perfectly distinguished from one another.

Ah! I had better say a system of connections rather than a system of relations.

The purpose of a Diagram is to represent certain relations in such a form that it can be transformed into another form representing other relations involved in those first represented and this transformed icon can be interpreted in a symbolic statement.

It is necessary that the Diagram should be an Icon in which the inferred relation should be perceived. And it is necessary that it should be insofar General that one sees that accompaniments are no part of the Object.

The Diagram is an Interpretant of a Symbol in which the signification of the Symbol becomes a part of the object of the Icon.

No other kind of sign can make a Truth evident for the evident is that which is presented in an image, leaving for the work of the understanding merely the Interpretation of the Image in a Symbol.

In the contents of consciousness we recognize three sorts of elements, Firstness, Secondness, Thirdness. A First is whatever it is in itself regardless of all else whether exterior to it or parts of it. [—] Firstness is feeling-quality; secondness is brute reaction; thirdness is mediation.

Firstness is the Mode of Being of that which is such as it is positively and regardless of anything else. It is thus an abstract possibility, It can therefore only be known to us immediately.

…logic is merely the science of ideas considered as signs.

A purely contentless principle. As a logical principle should be.

The consideration of the general way in which the mind, if it is to act deliberately and under self-control, must respond to the blows of experience […] gives Normative Science.

The general survey of the building-materials, the elements out of which concepts are to be built. Let us give this work the name of phaneroscopy.

2. Cenoscopy, the study of the experience already acquired.

In the contents of consciousness we recognize three sorts of elements, Firstness, Secondness, Thirdness. [—] What a Second is depends partly on another, but is regardless of any third, and thus of any reason. [—] Firstness is feeling-quality; secondness is brute reaction; thirdness is mediation.

Secondness is the Mode of Being of that which is such as it is relatively to a Second but regardless of any third. That makes it of a brute nature.

A sign is a species of medium of communication.

The object, O, determines the sign, S, and S determines the Interpreting sign, I, to being determined by O through S.

A sign is a Priman which is Secundan to an Object and is Tertian in determining an Interpretant into Secundanity to that Object.

In the contents of consciousness we recognize three sorts of elements, Firstness, Secondness, Thirdness. [—] What a Third is depends on two other things between which it mediates. Firstness is feeling-quality; secondness is brute reaction; thirdness is mediation.

Tertiality is the Mode of Being of anything insofar as it is such as it is to a Second for a Third.
