The new method of intellectual development among children being investigated represents a trilogy of mind, whose main thinking operation is the logical operation of comparison. The method was created due to Aristotle's understanding of philosophy as "the science about the first reasons and origins" of cognition--types of opposition which should be the beginning of the surrounding world's cognition at school. As they were discovered and set in a natural line of comparative notions, the main Plato's plan was fulfilled to reduce all particular laws to the general and to withdraw all particular laws from the general one (Plato 1993). As a result, we are talking about the building of stepwise transmission from one general notion to another more general notion that identifies the diversity of natural and social differences. As a result, it turned out to be possible to divide the whole thinking process into three related logical parts, each of which is determined by the advantageous usage of three types of cognitive means: (1) Reasonable thinking is the thinking with the help of classification notions on the basis of relations of "abstract identity" and "abstract difference", which determine the law of noncontradiction: either A, or not A; (2) Mental concrete-general metaphysical thinking is the thinking with the help of classification, quantitative, and comparative notions on the basis of the relation of "corresponding" and variety of mathematical and physical abstractions of different complexity being studied at school; and (3) Mental concrete-general dialectical thinking is the thinking with the help of classification and comparative notions on the basis of relation of "opposition" which allows to cognize natural and social processes. In addition to the generally accepted study of reasonable and mental thinking among schoolchildren with the help of concrete sciences, the new philosophical method is an effective means of advanced development of mental thinking among children, which makes for the holistic perception of the surrounding world by schoolchildren. 展开更多

The success of the Hunger Games trilogy to the young readers is its distinctive blending of science fiction elements with protagonist Katniss' initiation. The trilogy suffices youth's interest to embrace a fiction that dramatizes both realistic and fantastic portray of the world. Through depicting the intellectual and social development of protagonist Katniss who, after experiencing both defeats and triumphs in a dystopian world, Suzanne Collins successfully conveys the coming-of-age theme under the veil of science fiction in the Hunger Games trilogy. 展开更多
