Problem of critiries of thinking and perception laws adequecy to the “real” existence of ideal

The task of the article consists in establishing the criteria of logic laws assessment. In respect to the set task a complex of research methods is used: methods of dialectics, comparative analysis, and classification. Special attention is drawn to the necessity of grounding application of traditional logic laws in new spheres of scientific investigations. The work gives a detailed analysis of materials on boundaries of law of excluded middle application. On the basis of the brought material it is determined that the law of excluded middle cannot be abstracted from the mathematics of infinite aggregate. While analysing the logic criteria there appeared the whole range of moments. Laws of logic present a general result of public practice and perception. The latter gives the priority to the laws of logic in case of individual thinking process deviation from them. Not the laws of logic correct themselves in accordance with an individual thinking process but an individual thinking process corrects itself in accordance with the laws of logic. It is separately noted that this correlation can be modified if an individual thinking process has not a banal mistake but limitation of logic law and its non-compliance with the existence are established and grounded. In the end of the article the author makes a conclusion that an assessment of logic law adequacy requires taking into account experience of specific sciences.
