This paper is a reflection on some of Elizabeth Anscombe's influential work on causation, in particular on some comments in her Inaugural Lecture at Cambridge, published as ‘Causality and Determination’. One of Anscombe's major concerns in that paper is the relation between causation and necessitation, and she critically discusses the cast of mind which links causality with some kind of necessary connection or with exceptionless generalisation. In place of a semi-technical analysis of causation, Anscombe identifies the obvious and yet little considered core of the causal relation as follows

This paper offers an interpretation of the arguments Aristotle offers in "Metaphysics" 9.4, 1047b14-30, for the two modal theses [1] if (if A is the case then B is the case) then (if A is possible then B is possible) [2] if (if A is possible then B is possible) then (if A is the case then B is the case) Aristotle's arguments for these theses have not typically impressed commentators. I offer two arguments which are relatively faithful to Aristotle's text. The arguments rest on the following pair of claims concerning conditionals and possibility respectively [COND] 'if A then B' is true if and only if in any circumstances in which A obtains, B obtains also [TEST] 'possibly A' is true in a range of circumstances C1... $\text{C}_{\text{n}}$ if and only if assuming A true in any C1 gives rise to no impossibilities, once any further required adjustments are taken into account The arguments and the premises on which they rest are stated without formalisation of the theses [1] and [2]. The argument for [1] is a defensible and persuasive argument. The argument for [2] is invalid, though plausible. That is consistent with our differential verdicts on [1] and [2]. [2] appears to be false: the argument provided for [2] explains why Aristotle might nevertheless have asserted it. The aim of the paper is to justify a more positive verdict on Aristotle's arguments than is usual among commentators

In this lucid and insightful study, Stephen Makin investigates a form of argument widespread in ancient Greek philosophy, where the absence of a reason for one alternative to be the case rather than another is used to establish substantive conclusions—where the alternatives are “indifferent”. Examples abound: Anaximander engages in such reasoning to show that the Earth does not move; Zeno of Elea to show that what is cannot be divided; Democritus to argue for finite divisibility, on the one hand, and the infinite variety of atoms and worlds, on the other; not to mention the extensive use of such arguments in ancient skepticism.
