Feste: What is the opinion of Pythagoras concerning wildfowl? Malvolio: That the soul of our grandam might haply inhabit a bird. Act V

Pythagoras conceived that the first attention that should be given to men should be addressed to the senses, as when one perceives beautiful figures and forms, or hears beautiful rhythms and melodies. Consequently he laid down that the first erudition was that which subsists through music's melodies and rhythms, and from these he obtained remedies of human manners and passions, and restored the pristine harmony of the faculties of the soul.
iamblichus of chalcisIt seems probable that the early Greeks were largely indebted to the Phoenicians for their knowledge of practical arithmetic or the art of calculation, and perhaps also learnt from them a few properties of numbers. It may be worthy of note that Pythagoras was a Phoenician; and according to Herodotus , but this is more doubtful, Thales was also of that race.
Geometry has two great treasures; one is the Theorem of Pythagoras; the other, the division of a line into extreme and mean ratio. The first we may compare to a measure of gold; the second we may name a precious jewel.
johannes keplerPythagoras, when he was asked what time was, answered that it was the soul of this world.
PlutarchThere are men and gods, and beings like Pythagoras.
pythagorasPythagoras said that this world was like a stage, Whereon many play their parts; the lookerson, the sage Philosophers are, saith he, whose part is to learn The manners of all nations, and the good from the bad to discern.
As great Pythagoras of yore, Standing beside the blacksmith's door, And hearing the hammers, as they smote The anvils with a different note, Stole from the varying tones, that hung Vibrant on every iron tongue, The secret of the sounding wire, And formed the sevenchorded lyre.
Henry Wadsworth LongfellowAs soon as we venture on the paths of the physicist, we learn to weigh and measure , to deal with time and space and mass and their related concepts, and to find more and more our knowledge expressed and our needs satisfied through the concept of number , as in the dreams of Plato and Pythagoras .

There remains no firm basis for the belief that Pythagoras was a geometer and in any case no attestation of his having written anything.
The apparently ancient reports of the importance of Pythagoras and his pupils in laying the foundations of mathematics crumble on touch, and what we can get hold of is not authentic testimony by the efforts latecomers to paper over a crack, which they obviously found surprising, by the use of various kinds of reconstruction and reinterpretation. On the other hand, there are ancient and unassailable indications of a Greek mathematics antedating Pythagoras and quite outside his sphere of influence.
Pythagoras is the founder of European culture in the Western Mediterranean sphere.
It is impossible to decide whether a particular detail of the Pythagorean universe was the work of the master, or filled in by a pupil a remark which equally applies to Leonardo or Michelangelo . But there can be no doubt that the basic features were conceived by a single mind; that Pythagoras of Samos was both the founder of a new religious philosophy, and the founder of Science, as the word is understood today.
Arthur KoestlerPersonal religion is derived from ecstasy, theology from mathematics, and both are to be found in Pythagoras.
What seems certain is that Pythagoras developed the idea of mathematical logic... He realized that numbers exist independently of the tangible world and therefore their study was untainted by inaccuracies of perception. This meant he could discover truths which were independent of opinion of prejudice and which were more absolute then any previous knowledge.
