Quotations

Number rules the universe.

As quoted in Comic Sections (1993) by Desmond MacHale

Number is the ruler of forms and ideas, and the cause of gods and demons.

As quoted in Collection of Pythagorean Doctrines by Iamblichus of Chalcis

Time is the soul of this world.

As quoted in Wisdom (2002) by Desmond MacHale :Quotes cited as from the "Golden Verses", but drawn from various translations.

Work at these things, practice them, these are the things you ought to desire; they are what will put you on the path of divine virtue — yes, by the one who entrusted our soul with the tetraktys, source of ever-flowing nature. Pray to the gods for success and get to work.

Practice justice in word and deed, and do not get in the habit of acting thoughtlessly about anything.

As quoted in Divine Harmony : The Life and Teachings of Pythagoras by John Strohmeier and Peter Westbrook. (1999)

There is geometry in the humming of the strings. There is music in the spacings of the spheres.

As quoted in the preface of the book entitled Music of the Spheres by Guy Murchie (1961)

Other students who lived in neighboring areas were also permitted to attend Pythagoras's school. Known as Akousmatics, these students were permitted to eat meat and own personal belongings.

Pythagoras's followers were commonly called "Pythagoreans." For the most part we remember them as philosophical mathematicians who had an influence on the beginning of axiomatic geometry, which after two hundred years of development was written down by Euclid Euclid

.
The Pythagoreans observed a rule of silence called echemythia, the breaking of which was punishable by death. In his biography of Pythagoras Porphyry stated that this silence was "of no ordinary kind." The Pythagoreans were divided into an inner circle called the mathematikoi and an outer circle called the akousmatikoi . Porphyry wrote "the mathematikoi learned the more detailed and exactly elaborate version of this knowledge, the akousmatikoi those which had heard only the summary headings of his writings, without the more exact exposition." According to Iamblichus, the akousmatikoi were the exoteric disciples who listened to lectures that Pythagoras gave out loud from behind a veil. The akousmatikoi were not allowed to see Pythagoras and they were not taught the inner secrets of the cult. Instead they were taught laws of behavior and morality in the form of cryptic, brief sayings that had hidden meanings. The akousmatikoi recognized the mathematikoi as real Pythagoreans, but not vice versa. After the murder of Pythagoras and a number of the mathematikoi by the cohorts of Cylon, a resentful disciple, the two groups split from each other entirely, with Pythagoras's wife Theano and their two daughters leading the mathematikoi.

Theano, daughter of the Orphic initiate Brontinus, was a mathematician in her own right. She is credited with having written treatises on mathematics, physics, medicine, and child psychology, although nothing of her writing survives. Her most important work is said to have been a treatise on the principle of the golden mean. In a time when women were usually considered property and relegated to the role of housekeeper or spouse, Pythagoras allowed women to function on equal terms in his society.

The Pythagorean society is associated with strange and superstitious prohibitions, such as not to step over a crossbar, and not to eat beans . These rules seem like primitive superstition, similar to "walking under a ladder brings bad luck," rules one cannot help but sneeze at. The abusive epithet mystikos logos was hurled at Pythagoras even in ancient times to discredit him. The key here is that "akousmata" means "rules," so that the superstitious taboos primarily applied to the akousmatikoi, and many of the rules were probably invented after Pythagoras's death and independent from the mathematikoi . The mathematikoi placed greater emphasis on inner understanding than did the akousmatikoi, even to the extent of dispensing with certain rules and ritual practices. For the mathematikoi, being a Pythagorean was a question of innate quality and inner understanding.

Beans, black and white, were the means used in voting. The maxim "abstain from beans" was perhaps nothing more than an exhortation to not vote. If true, this would be an excellent example of how ideas can be distorted when heard second hand and taken out of context. There was also another way of dealing with the akousmata — by allegorizing them. We have a few examples of this, one being Aristotle Aristotle

Aristotle was an ancient Greek [i] philosopher [i], a student of Plato [i] ... 

's explanations of them: "'step not over a balance', i.e. be not covetous; 'poke not the fire with a sword', i.e. do not vex with sharp words a man swollen with anger, 'eat not heart', i.e. do not vex yourself with grief," etc. We have evidence for Pythagoreans allegorizing in this way at least as far back as the early fifth century BC. This suggests that the strange sayings were riddles for the initiated.

The Pythagoreans are known for their theory of the transmigration of souls, and also for their theory that numbers constitute the true nature of things. They performed purification rites and followed and developed various rules of living which they believed would enable their soul to achieve a higher rank among the gods. Much of their mysticism concerning the soul seem inseparable from the Orphic tradition. The Orphics advocated various purifactory rites and practices as well as incubatory rites of descent into the underworld. Pythagoras is also closely linked with Pherecydes of Syros, the man ancient commentators tend to credit as the first Greek to teach a transmigration of souls. Ancient commentators agree that Pherekydes was Pythagoras's most intimate teacher. Pherekydes expounded his teaching on the soul in terms of a pentemychos — the most likely origin of the Pythagorean use of the pentagram, used by them as a symbol of recognition among members and as a symbol of inner health .

It was the Pythagoreans who discovered that the relationship between musical notes could be expressed in numerical ratios of small whole numbers . The Pythagoreans elaborated on a theory of numbers the exact meaning of which is still debated among scholars.

Influence on Plato


Pythagoras or in a broader sense, the Pythagoreans, allegedly exercised an important influence on the work of Plato. According to R. M. Hare R. M. Hare

 and morals". c) Plato and Pythagoras shared a "mystical approach to the soul and its place in the material world". It is probable that both have been influenced by Orphism.

Plato's harmonics were clearly influenced by the work of Archytas, a genuine Pythagorean of the third generation, who made important contributions to geometry, reflected in Book VIII of Euclid's Elements.
