Photios I Quotes

Photios I, called the Great, was a Byzantine philosopher, theologian, and twice Patriarch of Constantinople, the most learned man of ninth-century Byzantium and one of the principal figures in the long Eastern Christian effort to harmonize the inheritance of classical philosophy with Christian theology. His Bibliotheca, an encyclopedia of summaries and excerpts from some 280 ancient works, has preserved much of what we know of late antique literature, while his Mystagogy of the Holy Spirit gave the classical Eastern Christian rebuttal of the Latin Filioque doctrine. The quotes below are attributed to Photios I, organized by topic.

Photios I on God

Attributed to Photios I:

“What the Latins have added to the Creed they have taken away from the truth.”

Photios I on Knowledge

Attributed to Photios I:

“The reading of the ancients is the duty of the educated Christian.”
Attributed to Photios I:

“The library is the treasury of the Christian commonwealth.”

“Tradition is preserved less by repeating it than by understanding why it was first said.”
“Jeremy Bernstein , Quantum Profiles (1991), "John Stewart Bell: Quantum Engineer”
The theory of the light quantum, which Einstein initiated in 1905 and which is with us still, is certainly the most revolutionary development in the history of physics and arguably in the history of science. The creators of the theory, men such as Einstein, Niels Bohr, Werner Heisenberg, Erwin Schrödinger, Wolfgang Pauli, and Paul Dirac, were often struck by the apparent "absurdity"—the utterly no
“Light is something like raindrops —each little lump of light is called a photon—and if the light is all one color , all the "raindrops" are the same.”
Richard Feynman , QED: The Strange Theory of Light and Matter (1985), p. 14.
“My favorite deep, elegant and beautiful explanation is Albert Einstein 's 1905 proposal that light consists of energy quanta, today called photons. Actually, it is little known, even among physicists, but extremely interesting how Einstein came to this position. It is often said that Einstein invented the concept to explain the photoelectric effect. Certainly, that is part of Einstein's 1905 publication, but only towards its end. The idea itself is much deeper, more elegant and, yes, more beautiful.”

Photios I on Mind

Attributed to Photios I:

“The unaided intellect strays; the intellect aided by the Spirit returns to itself.”

Photios I on Nature

“The theory of the light quantum, which Einstein initiated in 1905 and which is with us still, is certainly the most revolutionary development in the history of physics and arguably in the history of science. The creators of the theory, men such as Einstein, Niels Bohr, Werner Heisenberg, Erwin Schrödinger, Wolfgang Pauli, and Paul Dirac, were often struck by the apparent "absurdity"—the utterly noncommonsensical aspects—of the world depicted by the quantum theory.”

Photios I on Time

“All the indistinguishable photons illuminate the array of N slits, or grating, simultaneously. If only one photon propagates, at any given time, then that individual photon illuminates the whole array of N slits simultaneously.”
