2 The dual nature of man is still in our day a subject of vigorous debate. Reductionists are not willing to concede the existence of a soul. For them evidence of the immortal is anecdotal and talk of a soul figurative or explained as epiphenomenal. Socrates takes the soul’s existence as a given. Here the philosopher avoids undertaking a proof of the soul’s existence. This is what modern proponents must still do. In the scientific arena today such a claim is extraordinary and an extraordinary claim requires extraordinary evidence. Since the burden of proof lies with Socrates, he is obliged to side-step the issue.
