Context

“Living in an age when logic was beginning to mould human thought, Plato naturally cast his belief in immortality into a logical form. And when we consider how much the doctrine of ideas was also one of words, it is not surprising that he should have fallen into verbal fallacies: early logic is always mistaking the truth of the form for the truth of the matter. It is easy to see that the alternation of opposites is not the same as the generation of them out of each other; and that the generation of them out of each other, which is the first argument in the Phaedo, is at variance with their mutual exclusion of each other, whether in themselves or in us, which is the last.” source
