“The tradition of the oppressed teaches us that the “emergency situation” in which we live is the rule. We must arrive at a concept of history which corresponds to this. Then it will become clear that the task before us is the introduction of a real state of emergency; and our position in the struggle against Fascism will thereby improve. Not the least reason that the latter has a chance is that its opponents, in the name of progress, greet it as a historical norm. – The astonishment that the things we are experiencing in the 20th century are “still” possible is by no means philosophical. It is not the beginning of knowledge, unless it would be the knowledge that the conception of history on which it rests is untenable.”

“We say it is "explanation" but it is only in "description" that we are in advance of the older stages of knowledge and science. We describe better we explain just as little as our predecessors. We have discovered a manifold succession where the naive man and investigator of older cultures saw only two things "cause" and "effect " as it was said we have perfected the conception of becoming but have not got a knowledge of what is above and behind the conception. The series of "causes" stands before us much more complete in every case we conclude that this and that must first precede in order that that other may follow - but we have not grasped anything thereby. The peculiarity for example in every chemical process seems a "miracle " the same as before just like all locomotion nobody has "explained" impulse. How could we ever explain We operate only with things which do not exist with lines surfaces bodies atoms divisible times divisible spaces - how can explanation ever be possible when we first make everything a conception our conception It is sufficient to regard science as the exactest humanizing of things that is possible we always learn to describe ourselves more accurately by describing things and their successions. Cause and effect: there is probably never any such duality in fact there is a continuum before us from which we isolate a few portions - just as we always observe a motion as isolated points and therefore do not properly see it but infer it. The abruptness with which many effects take place leads us into error it is however only an abruptness for us. There is an infinite multitude of processes in that abrupt moment which escape us. An intellect which could see cause and effect as a continuum which could see the flux of events not according to our mode of perception as things arbitrarily separated and broken - would throw aside the conception of cause and effect and would deny all conditionality.”

“We believe that it is possible for scientific work to gain some knowledge about the reality of the world, by means of which we can increase out power and in accordance with which we can arrange our life. If this belief is an illusion, then we are in the same position as you. But science has given us evidence by its numerous and important successes that it is no illusion.”

“All significant concepts of the modern theory of the state are secularized theological concepts not only because of their historical development - in which they were transferred from theology to the theory of the state, whereby, for example, the omnipotent god became the omnipotent lawgiver - but also because of their systematic structure, the recognition of which is necessary for a sociological consideration of these concepts. The exception in jurisprudence is analogous to the miracle in theology. Only by being aware of this analogy can we appreciate the manner in which the philosophical ideas of the state developed in the last centuries.”

“To understand what happens now one must find the cause, which may be very long ago in its beginning, but is surely there, and therefore a knowledge of history as detailed as possible is essential if we are to comprehend the present and be prepared for the future.”

“The 'Manifesto' being our joint production, I consider myself bound to state that the fundamental proposition which forms its nucleus belongs to Marx. That proposition is: that in every historical epoch, the prevailing mode of economic production and exchange, and the social organization necessarily following from it, form the basis upon which is built up, and from which alone can be explained, the political and intellectual history of that epoch; that consequently the whole history of mankind (since the dissolution of primitive tribal society, holding land in common ownership) has been a history of class struggles, contests between exploiting and exploited, ruling and oppressed classes; that the history of these class struggles forms a series of evolution in which, nowadays, a stage has been reached where the exploited and the oppressed class—the proletariat—cannot attain its emancipation from the sway of the exploiting and ruling class—the bourgeoisie—without, at the same time, and once for all, emancipating society at large from all exploitation, oppression, class distinctions and class struggles.This proposition, which, in my opinion, is destined to do for history what Darwin's theory has done for biology, we, both of us, had been gradually approaching for some years before 1845.”
