“As in geometry, the oblique must be known, as well as the right; and in arithmetic, the odd as well as the even; so in actions of life, who seeth not the filthiness of evil, wanteth a great foil to perceive the beauty of virtue.”

— Philip Sidney

“If geometry exists, arithmetic must also needs be implied”

Nicomachus (60–120) Ancient Greek mathematician

Nicomachus of Gerasa: Introduction to Arithmetic (1926)
Context: If geometry exists, arithmetic must also needs be implied... But on the contrary 3, 4, and the rest might be 5 without the figures existing to which they give names. Hence arithmetic abolishes geometry along with itself, but is not abolished by it, and while it is implied by geometry, it does not itself imply geometry.<!--Book I, Chapter IV

“Words, as is well known, are the great foes of reality.”

Joseph Conrad book Under Western Eyes

Pt. I
Source: Under Western Eyes (1911)
Context: Words, as is well known, are the great foes of reality. I have been for many years a teacher of languages. It is an occupation which at length becomes fatal to whatever share of imagination, observation, and insight an ordinary person may be heir to. To a teacher of languages there comes a time when the world is but a place of many words and man appears a mere talking animal not much more wonderful than a parrot.
