Book by an outstanding British thinker of the 20th century. Bertrand Russell is devoted to a complex of logical-philosophical and theoretical-cognitive problems, which, in the traditions of British empiricism, were intensively discussed in the 30s and 40s in line with analytical philosophy. The author examines a wide range of issues related to experimental knowledge, truth, and the functioning of language as a means of cognition. On many issues, Russell expresses original judgments that are not found in other adherents of analytical philosophy.

The book will be read with interest by everyone interested in the empirical trends of philosophy of the 20th century, analytical philosophy and the philosophy of ordinary language.
