“The world's present industrial civilization is handicapped by the coexistence of two universal, overlapping, and incompatible intellectual systems: the accumulated knowledge of the last four centuries of the properties and interrelationships of matter and energy; and the associated monetary culture which has evolved from folkways of prehistoric origin.The first of these two systems has been responsible for the spectacular rise, principally during the last two centuries, of the present industrial system and is essential for its continuance. The second, an inheritance from the prescientific past, operates by rules of its own having little in common with those of the matter-energy system. Nevertheless, the monetary system, by means of a loose coupling, exercises a general control over the matter-energy system upon which it is superimposed.Despite their inherent incompatibilities, these two systems during the last two centuries have had one fundamental characteristic in common, namely exponential growth, which has made a reasonably stable coexistence possible. But, for various reasons, it is impossible for the matter-energy system to sustain exponential growth for more than a few tens of doublings, and this phase is by now almost over. The monetary system has no such constraints, and according to one of its most fundamental rules, it must continue to grow by compound interest.”

Context: The fall of meteoric stones was occasionally reported by good witnesses during many ages. But science did not understand how stones should be formed in or beyond the atmosphere... The accounts of the fall of meteoric stones were held to be incompatible with the laws of nature, and specimens which had been seen to fall by hundreds of people were preserved in cabinets of natural history as ordinary minerals, 'which the credulous and superstitious regarded as having fallen from the clouds.' A committee of the French Academy of Sciences, including the celebrated Lavoisier, unanimously rejected an account of three nearly contemporary descents of meteorites which reached them on the strongest evidence. After two thousand years of incredulity, the truth in this matter was forced upon the scientific world about the beginning of the present century. There would have been at any time, of course, an instant cessation of skepticism if any one could have shewn, a priori, from ascertained principles in connection with the atmosphere, how stones were to be expected to fall from the sky. But what is this but to say that facts by themselves, however well attested, are wholly useless in such circumstances to the cultivators of physical science, while any kind of vague hypothesis can be brought forward in opposition to them? What is it but to put conjecture or prejudice above fact, and indeed utterly to repudiate the Baconian method?

Le même esprit ne dure que deux cents ans.

Context: Modern industrial civilization has developed within a certain system of convenient myths. The driving force of modern industrial civilization has been individual material gain, which is accepted as legitimate, even praiseworthy, on the grounds that private vices yield public benefits, in the classic formulation. Now, it has long been understood, very well, that a society that is based on this principle will destroy itself in time. It can only persist, with whatever suffering and injustice that it entails, as long as it is possible to pretend that the destructive forces that humans create are limited, that the world is an infinite resource, and that the world is an infinite garbage can. At this stage of history either one of two things is possible. Either the general population will take control of its own destiny and will concern itself with community interests, guided by values of solidarity, sympathy and concern for others, or alternatively there will be no destiny for anyone to control. As long as some specialized class is in a position of authority, it is going to set policy in the special interests that it serves. But the conditions of survival, let alone justice, require rational social planning in the interests of the community as a whole, and by now that means the global community. The question is whether privileged elite should dominate mass communication and should use this power as they tell us they must—namely to impose necessary illusions, to manipulate and deceive the stupid majority and remove them from the public arena. The question in brief, is whether democracy and freedom are values to be preserved or threats to be avoided. In this possibly terminal phase of human existence, democracy and freedom are more than values to be treasured; they may well be essential to survival.
