Inhumanity may refer to:the opposite of humanity "Man's inhumanity to man", a phrase first documented in 1784
Indeed there is already a real perceptible danger that, while man's dominion over the world of things is making enormous advances, he should lose the essential threads of his dominion and in various ways let his humanity be subjected to the world and become himself something subject to manipulation in many ways – even if the manipulation is often not perceptible directly – through the whole of the organization of community life, through the production system and through pressure from the means of social communication. Man cannot relinquish himself or the place in the visible world that belongs to him; he cannot become the slave of things, the slave of economic systems, the slave of production, the slave of his own products. A civilization purely materialistic in outline condemns man to such slavery, even if at times, no doubt, this occurs contrary to the intentions and the very premises of its pioneers. The present solicitude for man certainly has at its root this problem. It is not a matter here merely of giving an abstract answer to the question: Who is man? It is a matter of the whole of the dynamism of life and civilization. It is a matter of the meaningfulness of the various initiatives of everyday life and also of the premises for many civilization programmes, political programmes, economic ones, social ones, state ones, and many others.
