“Every mind-mass strives to produce a like formed mind-mass and accordingly strives to produce that form of motion of the matter by which it was formed.”

Bernhard Riemann (1826–1866) German mathematician

Gesammelte Mathematische Werke (1876)

“Forming mind-masses amalgamate, combine or compound themselves in definite degree, partly with each other, partly with older mind-masses. The manner and strength of these combinations depend on conditions which are but imperfectly recognised by Herbart… They depend chiefly upon the inner relationship of the mind-masses.”

Bernhard Riemann (1826–1866) German mathematician

“All active mass movements strive, therefore, to interpose a fact-proof screen between the faithful and the realities of the world”

Eric Hoffer book The True Believer

Section 56
The True Believer (1951), Part Three: United Action and Self-Sacrifice
Context: The readiness for self-sacrifice is contingent on an imperviousness to the realities of life.... For self-sacrifice is an unreasonable act.... All active mass movements strive, therefore, to interpose a fact-proof screen between the faithful and the realities of the world.... by claiming that the ultimate and absolute truth is already embodied in their doctrine and that there is no truth nor certitude outside it.... To rely on the evidence of senses and of reason is heresy and treason. It is startling to realize how much unbelief is necessary to make belief possible. What we know as blind faith is sustained by innumerable unbeliefs.

“An immediate consequence of these principles of explanation is that the souls of organic beings, i. e., the compacts of mind-masses, arisen during life, continue to exist after death. (Their isolated persistence is not sufficient). But in order to explain the orderly development of organic nature in which the earlier collected experiences obviously serve as basis for the later creations, it is necessary to assume that these mind-masses enter into a greater compact of mind-masses, the Earth-Soul, and that these serve a higher soul-life according to the same laws as the mind-masses engendered in our nerve-processes observe in their service of our own soul-life.”

Bernhard Riemann (1826–1866) German mathematician

Gesammelte Mathematische Werke (1876)

“The soul is a compact of mind-masses combined in a most intimate and manifold manner. It grows constantly by accession of mind-masses, and upon these depend its development.”

Bernhard Riemann (1826–1866) German mathematician

Gesammelte Mathematische Werke (1876)

“Gravitation is not only similar to inertia in its generality, it is also measured by the same number… the mass. The inertial mass is what Newton calls the "quantity of matter": it is a measure for the resistance offered by a body to a force trying to alter its state of motion. It might be called the "passive mass." The gravitational mass, on the other hand, is a measure of the force exerted by the body in attracting other bodies. We might call it the "active" mass. The equality of active and passive, or gravitational and inertial, mass was in Newton's system a most remarkable accidental co-incidence, something like a miracle. Newton himself decidedly felt it as such, and made experiments to verify it, by swinging a pendulum with a hollow bob which could be filled with different materials. The force acting on the pendulum is proportional to its gravitational mass, the inertia to its inertial mass: the period of its swing thus depends on the ratio between these two masses. The fact that the period is always the same therefore proves that the gravitational and inertial masses are equal.”

“Freedom of mind and mind itself have been most fully developed in regions where trade developed at the same time. In all ages, without exception, every intense production of art, ideas, and spiritual values has occurred in some locality where a remarkable degree of economic activity was also manifest.”

Paul Valéry (1871–1945) French poet, essayist, and philosopher

“My religion consists of an humble admiration for the vast power which manifests itself in that small part of the universe which our poor, weak minds can grasp!”

Albert Einstein (1879–1955) German-born physicist and founder of the theory of relativity

1930s, Wisehart interview (1930)
Context: I do not believe in a God who maliciously or arbitrarily interferes in the personal affairs of mankind. My religion consists of an humble admiration for the vast power which manifests itself in that small part of the universe which our poor, weak minds can grasp!

“Above all things the mass-mind is most bitterly resentful of superiority. It will not tolerate the thought of an elite; and under a political system of universal suffrage, the mass-mind is enabled to make its antipathies prevail.”

Albert Jay Nock (1870–1945) American journalist

“MIND, n. A mysterious form of matter secreted by the brain. Its chief activity consists in the endeavour to ascertain its own nature, the futility of the attempt being due to the fact that it has nothing but itself to know itself with.”

Ambrose Bierce (1842–1914) American editorialist, journalist, short story writer, fabulist, and satirist

“The simplest and most common manifestation of the activity of older mind-masses is Reproduction, which consists in the striving of the active mind-mass to engender one similar to itself.”
