This paper examines Plato's ideas on cause-effect relations in the "Phaedo." It maintains that he sees causes as things (not events, states of affairs or the like), with any information as to how that thing brings about the effect relegated to a strictly secondary status. This is argued to make good sense, so long as we recognise that aition means the "thing responsible" and exploit legal analogies in order to understand what this amounts to. Furthermore, provided that we do not (...) pre-suppose that we already know what can and what cannot count as a cause, Plato proves to have an attractive case for his principle that all causation is a matter of like causing like. Once we appreciate this, we are a little closer to understanding his more idiosyncratic principle, which although puzzling is ubiquitous in his writings and often invoked as a premise in key arguments, that opposites cannot cause opposites. The last part of the paper turns to formal causes, defending Plato's advocacy of them, and examining their role in the "Parmenides'" Third Man Argument. The main proposal is that Plato's conception of Forms as causes opens the door to a better version of that argument's "Non-identity" premise than those currently available. (shrink)

An analysis of phaedo 96c-606c seeks to demonstrate that when forms are cited as either "safe" or "clever" aitiai they are not meant to function as either final or efficient causes, But as logico-Metaphysical essences which have no causal efficacy whatever, But which do have definite (and far-Reaching) implications for the causal order of the physical universe, For it is assumed that a causal statement, Such as "fire causes heat" will be true if, And only if, The asserted physical bond (...) between fire and heat instantiates the eternal and logically necessary relation of entailment between the instantiated forms, Fire, Heat.
