851. Rough Draught of Preface to Logical Criticism of Essential Articles of Religious Faith
A. MS., n.p., April 23, 1911, 1 p.
The spirit of science and the spirit of religion are opposed. Religious life must begin in feeling.

A. MS., n.p., April 25-May 21, 1911, pp. 1-15 unfinished; 6-14 of a discarded draft; plus 6 pp. also discarded.
CSP's plan to divide his book into two parts, one part concerned with logical critic and the other with the application of the principles of logical critic to religious questions. The meaning of "philosophy" as "a heuritic science of categorical truth." Philosophy based upon the common experience of all mankind. Doubt and belief opposed. Positive and negative doubt distinguished, with negative doubt regarded as the mere absence of belief. The meaning of "real"; its Latin derivation. Reality and hallucinatory experience. Common sense and critical common sense. Verbs and the Basque language (p. 15).

856. A Logical Criticism of the Articles of Religious Belief
A. MS., n.p., 2 pp. of one of the alternative sections are dated April 5 and 7, 1911, pp. 1-18, with several alternative sections.
The contempt for religious faith in scientific circles reveals, not open-mindedness, but prejudice. Deduction, induction, and retroduction are the only kinds of reasoning. Deduction as either necessary or probable. Determinism and free will. Over-specialization on the part of the average scientist has made him culturally ignorant - a queer mixture of enlightenment and of what is the equivalent of superstition. Laws of nature. Miracles and ultramiracles. Two of the alternative sections contain a discussion of existential graphs.

857. Lecture I
A. MS., n.p., n.d., pp. 1-5, incomplete.
This is the first lecture of the course planned in MS. 876. Double purpose of lecture: (1) to determine what a reasonable mind of the day ought to think of religion and (2) to comment on the validity of reasoning in general. Three and only three kinds of reasoning. Abduction, or retroduction. CSP's objectivity on the question of God's existence. If there is an Absolute, it is nothing like God.

858. An Essay on the Limits of Religious Thought written to prove that we can reason upon the nature of God
A. MS., n.p., n.d., 8 pp.
There are two dates on the verso of one of the pages: April 10, 1857 and January 11, 1861. The possibility of giving intelligible definitions of things which themselves can not be comprehended. Is the definition of "infinite" possible? The three necessary modes of dependency are community, causality, and influx. The three perfect degrees of modality are possibility, actuality, and necessity. All degree admits of one of three successive degrees: nullity, positivity, and perfection. All stages have one of three temporal expressions: retrogression, contemporaniety, or succession. The three intuitions of expression. The three total quantities of intuition and the three infinite qualities of quantity. Lastly, the three influxual dependencies of quality: negation, reality, infinity.

Sample: "Best maxim in writing, perhaps, is really to love your reader for his own sake." These aphorisms were apparently transcribed by CSP from various other writings of his on several occasions. Entry number LXX, for instance, is dated 1866 Nov. 20, and reads: "What is not a question of a possible experience is not a question of fact." This seems to be a slight revision of an entry in the Logic Notebook (MS. 339), p. 11v also dated 1866 Nov. 20: "What is not a question of what can possibly be known is not a question of fact."

*922. [Notes for a Work on Metaphysics]
A. MS., n.p., [c.1862 with one page dated May 29, 1862], 41 pp.
The first book of this projected work would have had the title, "Principles of Metaphysical Investigation." Man as the measure of all things. Truth and the nature of faith. Refutation of transcendentalism. On language, form, and plasticity.

923. [Ten Irreducible Conceptions and their Combinations]
A. MS., n.p., 1860-62, 24 pp., with a typed copy of the page dated June 8, 1862.

924. A Treatise of the Major Premisses of the Science of Finite Subjects (Nature)
A. MS., n.p., August 5, 1864, 3 pp.
All reasoning can be represented syllogistically. The major premises - the principles of science - are the subjects of metaphysics. Metaphysics as theoretically essential to science.

925. [A Treatise of the Major Premisses of the Science of Finite Subjects]
A. MS., n.p., August 5, 1864, 3 pp.
Science relies on the assumption that observation has value beyond itself.
The need to discover some validity of the major premises given in sensation; otherwise assumption of the major premises is petitio principii.

926. A Treatise of the Major Premisses of Natural Science A. MS., n.p., n.d., 3 pp.
Major premises regarded as a priori, i.e., logically antecedent to all science. Judgments refer predicate to subject. The subject is assumed; the predicate is experienced. All judgment is inference.

927. Possible extensive relations of subject and predicate
A. MS., n.p., n.d., 9 pp.
Quantities, qualities, real predicates, relations, forms of fact, reasonableness, and creative potentialities are all related. Admixture of chemical notes.

928. Sketch of a New Philosophy
A. MS., n.p., n.d., 15 pp.
Reasoning and experimentation essentially analogous. Philosophy is committed to the notion that the processes of nature and thought are alike. Chance, law, and continuity. Mathematical and metaphysical axioms. The monism of modern psychology is materialistic. Eleven chapters contemplated, and these are outlined briefly.

929. [On the Study of Metaphysics]
A. MS., n.p., n.d., 2 pp.
The training metaphysicians receive today is compared unfavorably with the training they
received in the medieval universities.

* 930. [On the Meaning of "Real"]
A. MS., n.p., n.d., 20 pp., including variants, numbered from 4-45 but not continuously.
The difference between "would be" and "actually is" ("was," or "will be"). History of word "real"; Duns Scotus and Kant on the real; CSP's definition. Mode of consciousness and the taking on of habits.

931. Questions on Reality
A. MS., n.p., [1868], 48 pp., with 2 pp. of an earlier draft.
The earlier draft of 2 pp. is an outline draft of G-1868-2a. Twelve questions asked and answered dogmatically. The questions are concerned with the possibility of ultimate cognitions; immediate self-consciousness; knowledge of the external world; truth and the agreement of logical conclusion with information; contradiction as not always signifying falsity; matter as not necessary to reality; thought and signs; the meaning of the "unknowable." The later draft concerns the proper method for determining how we think; self-evidentness and self-consciousness; the perceived and the imagined; our knowledge of the external world; thinking and signs; signs of the unknowable. Is there any cognition which is absolutely incapable of being known? Have we any intuitions? Some of the questions raised in the earlier draft are raised again and this time answered less dogmatically.

932. Potentia ex Impotentia
A. MS., n.p., [1868], 9 pp. of two drafts.
Questions concerning reality. The future of metaphysics depends upon its establishing a connection with tangible external facts. Defense of the view that no sign means anything essentially incognizable. On knowledge of things-in-themselves. Idealism and first impressions of sense.

933. [Reality, Being, and Figment]
A. MS., n.p., n.d., 7 pp. (but not continuous).
Reality and figment not equated with Being and nothing. A figment is something, and therefore comes under the heading of Being.

* 934. [Reality of the Universe]
A. MS., n.p., n.d., pp. 24-29.
Primary qualities and feelings. Phenomenalism and the relativity of knowledge. Being, accident, substance. The passage from being to substance is mediated by conception of accident. The threefold nature of accident: quality, relation, representation. Quality is firstness; relation, secondness; representation, thirdness. Relations are of two great genera: (a) those whose ground is prescindable and (b) those whose ground is not.

935. [Notes on Idealism]
A. MS., n.p., [c.1873-77?], 4 pp.
Is it possible to conceive of anything which is not an object of thought? Defense of the central position of idealism, namely, that the actual or possible object of thought is an essential part of existence.

936. [Idealism, Mind and Matter, and the Principle of Continuity]
A. MS., n.p., n.d., 3 pp.
Leibniz as the first to set forth the law of continuity, which explains how mind and matter act upon each other. Matter as effete mind which is habit bound. An elevated theory of idealism.

* 937. The Connection between Mind and Matter
A. MS., G-c.1893-2, pp. 1-13, with a variant p. 8; plus an earlier draft of 10 pp.
Published in entirety as 6.272-277.

939. Notes on Portions of Hume's "Treatise of Human Nature"
A. MS., n.p., [1905], 44 pp. and 5 pp. of variants.
For the probable date of the manuscript, see S. P. Langley correspondence for a letter from CSP, dated June 1, 1905. CSP considers only Part IV, Sections 1 and 2 of the "Treatise." Criticism of Hume's analysis of reasoning leads to an exposition of his own views. Association of beliefs, acritical reasoning, and reasoning (abductive, inductive, and deductive). Reasoning as that special variety of action which is under self-control. Probability and certainty; genuine and counterfeit beliefs; indubitability of beliefs and instincts. Hume's nominalistic metaphysics in the context of the nominalist-realist dispute. Percept and perceptual judgment as well as existence and reality distinguished. Three grades of complexity of being, with the triadic mode the most complex. Three kinds of triadic relations: collectivity, energy, signs. The different kinds of signs.

944. Dottings for 8 Lectures (D8)
A. MS., n.p., n.d., 2 pp. (two attempts); plus a typed copy.
Hegel and CSP mean nearly the same thing by existence. CSP can almost accept Hegel's definition as the immediate unity of reflection-into-self and reflection-into-another (his reservation concerns reflection). Hegel misplaces existence by putting it under the first part of his Encyclopaedia (Logic) and under the second division (Wesen), whereas he places time under the second part (Nature). For CSP, time would first have had to be organized before nature could have begun.

945. Mems for 8 Lectures (M8)
A. MS., n.p., n.d., 2 pp.
The freedom of unbounded possibility (before time and space were organized). The nothing of the not yet being distinguished from the nothing of negation. Becoming. Quality is a sleeping, potential consciousness; quale-consciousness is a potential mode of being.
