The proposed volume includes articles by Solomon Maimon (1753-1800), published in various scientific and philosophical periodicals of that time and devoted to a wide range of problems - natural philosophy, anthropological, legal, psychological and ethical. Maimon addresses some of these problems in a number of letters addressed to the most prominent thinkers and writers of the era. In his thoughts, Maimon anticipates a number of trends that have developed in philosophy and science of the 19th-20th centuries.
