The philosophical account of epistemological and ontological
issues in creating, recording, sharing and using principal scientific and engineering
concepts. The notion and structure of the knowledge will be disused, a variety
of misinforming trends identified, examples of ambiguous concepts presented,
and the improved definitions are developed. The author criticised the existing
and proposed the new definitions for the concepts such as definition, philosophy,
ontology, and expanded on the importance of philosophical hypotheses for advances
in sciences.
