The notorious substratum results from substance-with-qualities; individuals-with-powers solves this [Harré/Madden]
9. Objects / D. Essence of Objects / 6. Essence as Unifier
In logic the nature of a kind, substance or individual is the essence which is inseparable from what it is [Harré/Madden]

10. Modality / A. Necessity / 6. Logical Necessity
Logical necessity is grounded in the logical form of a statement [Harré/Madden]
10. Modality / A. Necessity / 7. Natural Necessity
Natural necessity is not logical necessity or empirical contingency in disguise [Harré/Madden]
The relation between what a thing is and what it can do or undergo relate by natural necessity [Harré/Madden]
A necessity corresponds to the nature of the actual [Harré/Madden]
Natural necessity is when powerful particulars must produce certain results in a situation [Harré/Madden]

Counterfactuals are just right for analysing statements about the powers which things have [Harré/Madden]
10. Modality / C. Sources of Modality / 3. Necessity by Convention
If natural necessity is used to include or exclude some predicate, the predicate is conceptually necessary [Harré/Madden]
Having a child is contingent for a 'man', necessary for a 'father'; the latter reflects a necessity of nature [Harré/Madden]
10. Modality / C. Sources of Modality / 4. Necessity from Concepts
Is conceptual necessity just conventional, or does it mirror something about nature? [Harré/Madden]
There is a conceptual necessity when properties become a standard part of a nominal essence [Harré/Madden]

12. Knowledge Sources / B. Perception / 6. Inference in Perception
Inference in perception is unconvincingly defended as non-conscious and almost instantaneous [Harré/Madden]
12. Knowledge Sources / D. Empiricism / 2. Associationism
Humean impressions are too instantaneous and simple to have structure or relations [Harré/Madden]
13. Knowledge Criteria / E. Relativism / 3. Subjectivism

Is the perspectival part of the essence, or just a relation between beings? [Nietzsche]
'Perspectivism': the world has no meaning, but various interpretations give it countless meanings [Nietzsche]

Science investigates the nature and constitution of things or substances [Harré/Madden]
14. Science / C. Induction / 3. Limits of Induction
Conjunctions explain nothing, and so do not give a reason for confidence in inductions [Harré/Madden]
Hume's atomic events makes properties independent, and leads to problems with induction [Harré/Madden]
14. Science / C. Induction / 5. Paradoxes of Induction / b. Raven paradox
Contraposition may be equivalent in truth, but not true in nature, because of irrelevant predicates [Harré/Madden]
The items put forward by the contraposition belong within different natural clusters [Harré/Madden]
The possibility that all ravens are black is a law depends on a mechanism producing the blackness [Harré/Madden]
14. Science / D. Explanation / 1. Explanation / b. Aims of explanation
Explanation is just showing the succession of things ever more clearly [Nietzsche]
Only changes require explanation [Harré/Madden]
