Pythagoras, disregarded experience, [436]; see [Pythagoreans].
[Pythagoreans] had a two-fold doctrine — exoteric and esoteric, [52]; fascinated by particular numbers, [74]; their view of the soul, [449]; went astray in defining from numbers, [603]; ascribed perfection and beauty to results, not to their originating principles, [625]; said the Universe and all things are determined by Three, [630]; recognized Right and Left in the Heaven, [610]; erred in calling ours the upper hemisphere and to the right, [640]; affirmed harmony of the spheres, [646]; placed Fire, not Earth, at the centre of the Kosmos, [648]; made the Earth and Antichthon revolve each in a circle, [648].
