- (MARXISM) a phase or ‘moment’ in a dialectical process (see DIALECTIC) which negates a previous one, leading ultimately to a resolution (‘negation of the negation’). In the work of members of the FRANKFURT SCHOOL OF CRITICAL THEORY (especially ADORNO's Negative Dialectics, 1973) negativity was expressed as an opposition to all fixed categories and to the ‘administered world’ to which both orthodox Marxism and POSITIVISM were seen to lead.
Negation a philosophical category expressing a certain type of relationship between two consecutive stages or states of a developing object or process. Negation is a necessary part of development and of the struggle between opposites. In “its comprehension and affirmative recognition of the existing state of things,” the dialectic “includes, at the same time also, the recognition of the negation of that state, of its inevitable breaking up” (K. Marx, in K. Marx and F. Engels, Soch., 2nd ed., vol. 23, p. 22). As it develops, an object inevitably reaches the stage of its own negation: that is, it becomes qualitatively something other than itself. The negation of the old and the rise of the new constitute a chain without beginning or end. In this process, the developing object simultaneously becomes something other than itself and, in a certain sense, remains what it was. For example, youth negates childhood and is itself negated by maturity, which is negated by old age. At the same time, these are merely different stages in the development of the same person. This continual self-negation characterizes ongoing self-development in nature, society, and cognition. “True, natural, historical, and dialectical negation (taken formally) is precisely what constitutes the driving principle of all development—the splitting into antitheses, their struggle and resolution” (F. Engels, ibid., vol. 20, p. 640). Dialectical negation is, above all, creative negation, in which the old is not simply discarded and destroyed but “removed” (aufgehoben) and preserved in a new capacity. V. I. Lenin emphasized that an essential part of the dialectic is “negation as a moment of connection, as a moment of development, retaining the positive” (Poln. sobr. soch, 5th ed., vol. 29, p. 207). This “retention” of the positive, the unity of negation and continuity in development, is an important feature of dialectical negation as a universal principle of being, which manifests itself in different ways at different levels of the organization of matter.

Does the cooking have a negative effect on the protein content of the food? I have heard that high temperatures cooking breaks the protein, so does the cooking have a negative effect on the protein content of the food?A. Yes. Proteins can be denatured by heat, but only when the protein structure is delicate or is exposed to extremely high temperatures for long time. You must remember that breaking of protein is the physical-chemical process where the physical or chemical structure of a protein is rearranged. So cooking will not reduce on the nutritive value of the food until it’s cooked at cooking temperatures. More discussions about negationNegation
