“It is true that men themselves made this world of nations ... but this world without doubt has issued from a mind often diverse, at times quite contrary, and always superior to the particular ends that men had proposed to themselves.”
—Giambattista Vico (1688–1744)
“We operate exclusively with things that do not exist, with lines, surfaces, bodies, atoms, divisible time spans, divisible spaces—how could explanations be possible at all when we initially turn everything into images, into our images!”
—Friedrich Nietzsche (1844–1900)
