Friedrich Engels: The slave frees himself when, of all the relations of private property, he abolishes only the relation of slavery and thereby becomes a proletarian; the proletarian can free himself only by abolishing private property in general. https://wordsmith.social/protestation/quotes#quote9510
Karl Marx: The property-owning class and the class of the proletariat represent the same human self-alienation. But the former feels at home in this self-alienation and feels itself confirmed by it; it recognises alienation as its own instrument and in it it possesses the semblance of a human existence. The latter feels itself destroyed by this alienation and sees in it its own impotence and the reality of an inhuman existence. https://wordsmith.social/protestation/quotes#quote9511
Friedrich Engels: The so-called constants of physics are for the most part nothing but designations of the nodal points where quantitative addition or withdrawal of motion calls forth a qualitative change in the state of the body in question. https://wordsmith.social/protestation/quotes#quote9514
Friedrich Engels: ELECTRICITY, like heat, only in a different way, has also a certain omnipresent character. Hardly any change can occur in the world without it being possible to demonstrate the presence of electrical phenomena. If water evaporates, if a flame burns, if two different metals, or two metals of different temperature, touch, or if iron touches a solution of copper sulphate, and so on, electrical processes take place simultaneously with the more apparent physical and chemical phenomena. The more exactly we investigate natural processes of the most diverse nature, the more do we find evidence of electricity. In spite of its omnipresence, in spite of the fact that for half a century electricity has become more and more pressed into the industrial service of mankind, it remains precisely that form of motion the nature of which is still enveloped in the greatest obscurity. https://wordsmith.social/protestation/quotes#quote9515
