CHAPTER III
DEPENDENCY AND INDEPENDENCY
§ 2. In experimentation the determining factors are known before and the dependent factors only after the result of the experiment
§ 3. Errors in observation (unaided by experiment) resulting from the false supposition that certain factors are independent which are in reality dependent§ I. Inference (so-called) from particulars to particulars should be termed eduction
CHAPTER IV
EDUCTION
§ 2. Eduction involves a minor, middle and major premiss containing not only a minor and a major term but also two middle terms respectively intensional and extensional. Schematisations of eduction
§ 3. The commonly alleged distinction between induction and analogy should be replaced by the distinction between the two mediating terms respectively extensional and intensional required for eduction and for generalisation. Cases tabulated where all the evidential data are in favour of a certain educed conclusion
§ 4. In estimating the evidential force of instantial data, characters must be counted only so far as they constitute an independency, and instances only so far as they constitute a variancy
§ 5. Further explication of the above principle

CHAPTER V
PLURALITY OF CAUSES AND OF EFFECTS
§ 2. An assignment of Cause or of Effect is complete only in reference to the Effect or to the Cause
§ 3. A conjunction of cause-factors constitutes a completed cause; a conjunction of effect-factors constitutes a completed effect
§ 4. Plurality means that some but not all of the possible values of a determinable may be put into the subject-terms of the universals in which the same determinate character is predicated
§ 5. Correction of the demonstrative figures of induction required by the consideration of a possible plurality of causes or of effects
§ 6. Reversibility of the universal proposition connecting the completed cause and the completed effect
§ 7. The step-by-step process by which the completed cause and the completed effect are reached§ 1. Preliminary exposition of the notion of change in its reference to a Continuant
CHAPTER VI
CAUSE-FACTORS
§ 2. Continuant as Cause must be distinguished from Occurrent as Cause. Cause and Effect are coordinate when interpreted as Events and each is reciprocally inferable from the other. Nevertheless the temporal relation is regarded as not reciprocal
§ 3. Alleged distinction between two types of objective law
§ 4. The properties of continuants regarded as causal
§ 5. Effects -- like causes -- not merely resolvable into events or occurrences
§ 6. Temporal sequence of cause-occurrence and effect-occurrence explained in reply to philosophical criticism§ I. The fundamental notion of causal connection between movements that occur in space entails reference to a physical continuant conceived as that which moves
CHAPTER VII
THE CONTINUANT
§ 2. The term 'continuant' is chosen to replace 'substance' in order to free the notion from certain philosophical implications inseparable from the latter, and to emphasize the inevitable residuum which (as maintained by the writer) is indispensable for science. Thus, in the first place, the extension of continuance to an infinite future and an infinite past which is often attributed by philosophers to substance may be dispensed with in the scientifically conceived continuant
§ 3. Secondly, substantival continuance does not necessarily entail any adjectival changelessness
§ 4. Thirdly, the ultimate substantival continuant is not necessarily simple. Moreover, the existential components which mayconstitute a continuant-unity may not themselves be continuant
§ 5. What in general holds of the physical continuant holds also of the psychical continuant; but the structure of the latter exhibits far higher complexity than the former. For, whereas motion is the sole fundamental mode of manifestation of the physical continuant, there are many irreducible but interconnected modes of manifestation to be attributed to the psychical continuant. Within each of these several modes the conception of change must be separately applied
§ 6. The conception of change, moreover, involves the replacement of one by another manifestation, of which different determinate characters under the same determinable may be predicated
§ 7. The mutually implied conceptions of substance and causality (in their residual scientific significance) lead to the notion of property, which is the appropriate adjective characterising a continuant as contrasted with an occurrent. A property must be conceived as a defined potentiality: other adjectives are conceived as descriptive of actualities
§ 8. The comparatively primitive attempts to systematise the manifold of reality illustrate the same principles and postulates which govern the procedure of advancing science
§ 9. Sub-continuants and sub-occupants
§ 10. Causality within the manifestations of a single continuant
§ 11, Uniformities embracing different continuants
§ 12. The unity of a continuant exhibited in causal formulae. Alterable and unalterable properties
§ 13. Comparison of the views here maintained with those of Kant
§ 14. Fundamental contrast between the author's views and those widely current since Hume and at the present day§ I. The effect of purposive control in modifying the more mechanical mental processes points to a form of causality -- operating within the experience of a single individual -- which is closely analogous to the form of causality termed transeunt
CHAPTER VIII
APPLICATION OF CAUSAL NOTIONS TO MIND
§ 2. If there is any direct determining influence of the psychical upon the physiological or conversely, such influence undoubtedly comes under the head of transeunt causality. If, for example, we assume that sensations and other quasi-mechanical mental processes are directly determined by neural processes, there will be a direct correlation between such mental processes on the one hand and the neural processes on the other. If, further, we assume that the phases of feeling and cognition are partially determined by sensations, then there will be a partial -- but indirect -- correlation between the former and the latter. But such correlation must be limited to those variations which can be said to correspond with one another. And it would appear that there are no variations in neural process which could correspond to the variations of feeling and cognition
§ 3. Any felt effort or strain that may be incurred by mental activity has both a physiological and a sensational aspect which can properly be said to correspond. But so far as the effects of such effort are intended, we have reasonable ground for asserting the operation of transeunt causality, in which the causal agency is psychical and the direct effect physiological
§ 4. The presumption that foreknowledge operates in the psychical determination of physical effects, is tantamount to attributing real causal efficiency to such foreknowledge. But if this foreknowledge could be reduced to merely physiological terms, mental causality would be an illusion
§ 5. Mental activity assumes two distinct types. (1) Motor activity which produces sensational effects, and (2) The activity of attention which produces cognitional effects. In both cases, grounds are put forward for maintaining that the causal agency entailed is purely psychical
§ 6. Explicit grounds for the contention that changes of cognitive phase have no counterparts in the changes of neural process
§ 7. The prevalent confusion between images and ideas largely accounts for the refusal by physiologists and psychologists to accept the above view
§ 8. An analysis of the phases of consciousness accompanying reflex processes best illustrates the contrast between physiological and psychical causal agency
§ 9. But an analysis of conative conflict yields the most important indication that psychical agency is really causally operative
§ 10. The cognitive aspects of deliberative process complete the grounds for our main contention
§ 11. 'Judgments of value' stand to 'conations' as cause to effect, not conversely§ 1. The event termed 'Movement' cannot be reduced to merely spatio-temporal terms; since it requires something that moves, and that retains its continued identity within the spatio-temporal bounds of the event
CHAPTER IX
TRANSEUNT AND IMMANENT CAUSALITY
§ 2. The causality formulated in the first law of motion is wholly immanent, but that formulated in other dynamic laws is essentially transeunt
§ 3. Analysis of the immanent and transeunt factors entering into an elementary physical process
§ 4. Contrast to the previous illustration, where cause and effect are reversed. In cases of immanent process, where a cause-occurrent and an effect-occurrent are simultaneous, our ground for deciding which of the two occurrents is cause and which is effect is based upon the principle that that occurrent which is effect in the transeunt process is cause in the immanent process
§ 5. In the analysis of emotional experiences, which entail diffused organic sensations, another illustration is afforded of the ways in which transeunt and immanent causality are distinguished and combined
§ 6. Fundamental distinctions between the psychical and the physical continuant
§ 7. The finally unique distinction between the two
§ 8. Formulae which are correctly expressed in terms of immanent causality as regards unitary wholes are frequently equally correctly and more adequately expressed in terms also of transeunt causality as regards constituent parts§ 1. Diagrammatic representation, by the use of parallel, converging and diverging lines, to explain the different forms assumed in causal complexes, -- parallel lines being employed to represent causal independence
