“History presents a series of cultural epochs. Each is a span of years within which knowledge presents a more or less unified structure which can be expressed in a classification, but each new epoch requires a new classification.”

“…The present revolution of scientific thought follows in natural sequence on the great revolutions at earlier epochs in the history of science.”

Arthur Stanley Eddington (1882–1944) British astrophysicist

Einstein's special theory of relativity, which explains the indeterminateness of the frame of space and time, crowns the work of Copernicus who first led us to give up our insistence on a geocentric outlook on nature; Einstein's general theory of relativity, which reveals the curvature or non-Euclidean geometry of space and time, carries forward the rudimentary thought of those earlier astronomers who first contemplated the possibility that their existence lay on something which was not flat. These earlier revolutions are still a source of perplexity in childhood, which we soon outgrow; and a time will come when Einstein's amazing revelations have likewise sunk into the commonplaces of educated thought.

“It seems as though a new epoch were in preparation, a truly human epoch”

Maria Montessori (1870–1952) Italian pedagogue, philosopher and physician

Antropologia Pedagogica (1910), translated as Pedagogical Anthropology (1913), p. 259.
Context: It seems as though a new epoch were in preparation, a truly human epoch, and as though the end had almost come of those evolutionary periods which sum up the history of the heroic struggles of humanity; an epoch in which an assured peace will promote the brotherhood of man, while morality and love will take their place as the highest form of human superiority. In such an epoch there will really be superior human beings, there will really be men strong in morality and in sentiment. Perhaps in this way the reign of woman in approaching, when the enigma of her anthropological superiority will be deciphered. Woman was always the custodian of human sentiment, morality and honour, and in these respects man always has yielded women the palm.

“Peter the Hermit, Calvin, and Robespierre, each at an interval of three hundred years and all three from the same region, were, politically speaking, the Archimedean screws of their age, — at each epoch a Thought which found its fulcrum in the self-interest of mankind.”

Honoré de Balzac (1799–1850) French writer

Pierre l'Ermite, Calvin et Robespierre, chacun à trois cents ans de distance, ces trois Picards ont été, politiquement parlant, des leviers d'Archimède.C'était à chaque époque une pensée qui recontrait un point d'appel dans les intérêts et chez les hommes.
