The late John L. Mackie, formerly of University College, Oxford.

1. Causal knowledge is an indispensable element in science. Causal assertions are embedded in both the results and the procedures of scientific investigation. 2. It is therefore worthwhile to investigate the meaning of causal statements and the ways in which we can arrive at causal knowledge.

Annotation In this book Mr. Mackie selects for critical discussion six related topic which are prominent in John Locke's Essay concerning Human Understanding: ...

The paradoxical view of warnock and hodgson that act-Utilitarianism must have disutility is criticised. Simple examples in game theory style show that it does not defeat the possibility of cooperation and that it allows an approximation to truth-Telling. Promising would indeed have only a limited role in an act-Utilitarian society, But that is because its normal function is to aid compromise between divergent purposes. Also, The efforts of a single act-Utilitarian in a non-Act-Utilitarian society need not frustrate themselves, If he (...) is not too candid. (shrink)

In this chapter, Mackie presents a defence of Locke against Berkeley's attack on abstraction. It is argued that Locke's theory of ideas primarily concerns our ability to employ words and statements. Locke's theory concerning ideas of numbers is criticized. Three theories of universals are considered: realism, nominalism, and conceptualism; it is concluded, however, that the notion of there being distinct things with which we connect general words with particular things is mistaken. Mackie instead proposes a theory of general words being (...) ‘annexed’ to features of things. (shrink)

Mackie examines the distinction between primary and secondary qualities. It is argued that Locke's distinction supports the claim that he held a representative theory of perception. Mackie discussed Locke's arguments for the distinction. The relation of Locke's account to Molyneaux's problem is considered. Mackie critically compares his reformulation of the primary/secondary distinction with that of Jonathan Bennett.
