Abstract

ion and Ideation - The Semantics of chemical and biological fundamental concepts. The methods of abstraction and ideation are indispensable tools to introduce new concepts in a scientific terminology. The latter is paradigmatically introduced within the 'protophysical program' whereas abstraction is commonly applied in logics and mathematics. The application within the reconstruction of chemistry and biology causes several problems. Ideation appears to be inadequate whereas the application of abstraction necessitates a critical and minute examination of the corresponding equivalence relations. These problems are solved by the introduction of the method of materially-synthetic abstraction which is exemplified by the introduction of the chemical concept of 'substance' and the biological concept of 'hereditary factor'
