The Heart, the Soul, and Science

Here's a strange paragraph in an otherwise sensible essay:

One of the most important contributions a scientist can make is to successfully question opinions that seem self-evident and obvious to the public. Once it was commonly accepted in the West that the world was flat and that the heart was the residence of the soul.

And here's a good response:

Where's the evidence that the soul does not reside in the heart?

The debate continues here.
