"We worship God rightly if we render our intellect pure from all vice, as from some stain." Iamblichus, Exhortation to Philosophy Chapter 2 gnômê 11

Or haven’t you remembered that in that life alone, when he looks at Beauty in the only way that Beauty can be seen - only then will it become possible for him to give birth not to images (because he’s in touch with no images), but to true virtue (because he is in touch with the true Beauty). The love of the gods belongs to anyone who has given birth to true virtue and nourished it, and if any human being could become immortal, it would be he.

Plato, Symposium 212a

“First of all, then, show devotion to the gods, not merely by doing sacrifice, but also by keeping your vows; for the former is but evidence of a material prosperity, whereas the latter is proof of a noble character. Do honor to the divine power at all times, but especially on occasions of public worship; for thus you will have the reputation both of sacrificing to the gods and of abiding by the laws.” The Orations of Isocrates, To Demonicus 14

"Never step across the sweet-flowing water of ever-rolling rivers until you have prayed, gazing into the soft flood, and washed your hands in the clear, lovely water. Whoever crosses a river with hands unwashed of wickedness, the gods are angry with him and bring trouble upon him afterwards."

Hesiod, Works and Days 737-741

"It is well to invoke God at the beginning and end both of supper and dinner, not because he is in want of anything of the kind, but in order that the soul may be transfigured by the recollection of divinity. For since we proceed from him, and participate in a divine nature, we should honor him. Since also God is just, we should act justly in all things."

Diotogenes, On Sanctity

“No one is free who does not rule over himself.” The Pythagorean Sentences of Demophilus 32

"The sacrifices of fools are food for the fire, and the offerings which they bring supply the temple robbers."

The Pythagorean Sentences of Demophilus 22

The Platonic philosopher Iamblichus wrote a biography Life of Pythagoras. In the next series of posts, we will share quotes from this book as translated by Thomas Taylor.

“When it is considered that Pythagoras was the father of philosophy, authentic memoirs of his life cannot fail to be uncommonly interesting to every lover of wisdom, and particularly to those who reverence the doctrines of Plato, the most genuine and the best of all his disciples. And that the following memoirs of Pythagoras by Iamblichus are authentic, is acknowledged by all the critics, as they are for the most part obviously derived from sources of very high antiquity; and where the sources are unknown, there is every reason to believe, from the great worth and respectability of the biographer, that the information is perfectly accurate and true.”

Thomas Taylor, in his introduction to Iamblichus' Life of Pythagoras

“Indeed, no one can doubt that the soul of Pythagoras was sent to mankind from the empire of Apollo, either being an attendant on the God, or co-arranged with him in some other more familiar way: for this may be inferred both from his birth, and the all-various wisdom of his soul. And thus much concerning the nativity of Pythagoras.” Iamblichus, Life of Pythagoras Chapter 2

“Hence it was reasonably asserted by many, that he [Pythagoras] was the son of a God. But he being corroborated by renown of this kind, by the education which he had received from his infancy, and by his natural deiform appearance, in a still greater degree evinced that he deserved his present prerogatives. He was also adorned by piety and disciplines, by a mode of living transcendency good, by firmness of soul, and by a body in due subjection to the mandates of reason. In all his words and actions, he discovered an inimitable quiet and serenity, not being subdued at any time by anger, or laughter, or emulation, or contention, or any other perturbation or precipitation of conduct; but he dwelt at Samos like some beneficent dæmon.” Iamblichus, Life of Pythagoras Chapter 2

“He [Pythagoras] also formed a cavern out of the city, adapted to his philosophy, in which he spent the greatest part both of the day and night; employing himself in the investigation of things useful in disciplines, framing intellectual conceptions after the same manner as Minos the son of Jupiter. Indeed, he so much surpassed those who afterwards employed his disciplines, that they conceived magnificently of themselves, from the knowledge of theorems of small importance; but Pythagoras gave completion to the science of the celestial orbs, and unfolded the whole of it by arithmetical and geometrical demonstrations. He is, however, to be admired in a still greater degree for what he afterwards accomplished. For when now philosophy had received a great accession, he was admired by all Greece, and the best of those who philosophized came to Samos on his account, in order that they might participate of his erudition.” Iamblichus, Life of Pythagoras Chapter 5
