The purpose of this paper can be described as follows. The contemporary philosophical logic cannot work without using some terms well-known from mathematics and (mathematical) logic. Among such terms that play an important role in logical and philosophical analyses of language, meaning and the like we can find function, procedure and construction. One problem is that various authors use these terms in various ways, another problem consists in the well-known fact that many philosophers do not have any idea of what those and similar terms could mean. The present paper tries to explain why an exact explication of the three mentioned terms can contribute to understanding and even solving many problems with semantics of natural language, which a philosopher should be (and frequently is) interested in.

The aim of this communication is to prove that commonly used principle of exensionality (according to which the logical value of a complex sentence depends only on the logical values of sentences that are the parts of it) implies the fregean axiom. Moreover it has been presented in what sense the non-fregean logic is extensional.

We are often told that the meaning of a definiendum of an adequate definition is identical to the meaning of its definiens. This claim appears in Frege’s theory of definitions, and so it appears in Russell’s theory. However, it is worthwhile to remember both philosophers were advocates of the extensional semantics. Yet, the claim is often accepted beyond the realm of extensional theories. Admittedly, the claim is sustainable in the intensional semantics. However, as the author will argue, it is untenable in the theory of definitions based on hyperintensional semantics.
