“One ought to be "Marxist' with the same naturalness with which one is "Newtonian" in physics, or "Pasteurian" in biology, considering that if facts determine new concepts, these new concepts will never divest themselves of that portion of truth possessed by the older concepts they have outdated.”

— Ernesto Che Guevara

Ernesto Che Guevara 258

Argentine Marxist revolutionary 1928–1967

Aleksandr Zinovyev (1922–2006) Russian writer

On the Social State of Marxism (1978)

“The fundamental concept in social science is Power, in the same sense in which Energy is the fundamental concept in physics.”

Bertrand Russell (1872–1970) logician, one of the first analytic philosophers and political activist

“There is no concept in the whole field of physics which is more difficult to understand than is the concept of entropy, nor is there one which is more fundamental.”

Francis Sears (1898–1975) American physicist

[Francis Weston Sears, Mechanics, heat and sound, Addison-Wesley principles of physics series Volume 1, 2nd Edition, Addison-Wesley Press, 1950, 447]

“I believe our only hope for the future is to adopt a new conception of human ecology, one in which we start to reconstitute our concept of the richness in human capacity.”

Ken Robinson (1950) UK writer

“While the new physics was developing in the 20th century, the mechanistic Cartesian world view and the principles of Newtonian physics maintained their strong influence on Western scientific thinking, and even today many scientists still hold to the mechanistic paradigm, although physicists themselves have gone beyond it.
However, the new conception of the universe that has emerged from modern physics does not mean that Newtonian physics is wrong, or that quantum theory, or relativity theory, is right. Modern science has come to realize that all scientific theories are approximations to the true nature of reality; and that each theory is valid for a certain range of phenomena.”

“Our empirical criterion for a series of theories is that it should produce new facts. The idea of growth and the concept of empirical character are soldered into one.”

Imre Lakatos (1921–1974) Hungarian mathematician, philosopher

“To new concepts correspond, necessarily, new signs.”

David Hilbert Mathematical Problems

Mathematical Problems (1900)
Context: To new concepts correspond, necessarily, new signs. These we choose in such a way that they remind us of the phenomena which were the occasion for the formation of the new concepts.

“It would be very unsatisfactory if the new way of looking at the time-concept, which permits a Lorentz transformation, were to be confined to a single part of Physics.”

Hermann Minkowski The Fundamental Equations for Electromagnetic Processes in Moving Bodies

The Fundamental Equations for Electromagnetic Processes in Moving Bodies (1907)

“The whole history of man is continuous proof of the maxim that to divest one's methods of ethical concepts means to sink into the depths of utter demoralization.”

Emma Goldman book My Disillusionment in Russia

My Disillusionment in Russia (1923)
Context: The great and inspiring aims of the Revolution became so clouded with and obscured by the methods used by the ruling political power that it was hard to distinguish what was temporary means and what final purpose. Psychologically and socially the means necessarily influence and alter the aims. The whole history of man is continuous proof of the maxim that to divest one's methods of ethical concepts means to sink into the depths of utter demoralization. In that lies the real tragedy of the Bolshevik philosophy as applied to the Russian Revolution. May this lesson not be in vain.

“Something is beautiful if it is honest. If you do an engaged piece of work, which is sincere, the concept of beauty meets the concept of truth. So no illusive harmony. I try to reach people who strive for truth, for identity. Although these conceptions are incredibly warn out, one must try to find the way back to these simple conceptions.”

Jörg Immendorff (1945–2007) German artist
