So, if we find someone, following Pythagoras example, engaged in the pursuit of the knowledge and understanding of the transcendent and eternal, then it's reasonable to call that person a Pythagorean.

Those who wish to define a Pythagorean as a person who is deeply interested in the study of quantitative and qualitative reasoning appear to be promoting an incomplete definition, because it only covers a part of Pythagorean interest. In fact it only addresses some of the tools used to follow the totality of Pythagorean interest.

The first definition is to be preferred because it encompasses the totality of Pythagorean interest. Pythagoras' interests and significance are more than just being a patron of quantitative and qualitative reasoning. The mystical aspect of Pythagorean tradition and thought are what render Pythagoras unique, and give the basis for using the term Pythagorean.

If all you're interested in is good math, then it might be more appropriate to call yourself a Keplerian.
