The aim in the article is to explain why we fall in dualism of content and conceptual scheme. The dualism says that there is a relation between languages and the world (meant as an object). The first cause is mechanistic way of thinking which characterizes Indoeuropean mind. The way on thinking is to treat every object as if it had formal properties of physical objects. The term is taken from Whorf’s works. Concequences of mechanistic thinking for research in abstract sciences is considered. It is demonstrated how mechanistic thinking lets to pass from belief that there are some relations between expressions of a language and elements of the world to belief that there is a relation between the language as a whole and the whole world. The fallowing causes of the dualism are also considered: 1. literal understanding of metaphores used in philosophy of language, 2. wrong understanding of suppositions, 4. attempts to explain language in natural terms, e.g. causal theory of meaning.
