The creation as well as the dissemination and deployment of scientific knowledge is based chiefly on experience and logic, besides an essential role plays also the philosophical approach to empirical research and to logical treatment of empirical data. The symposium S003 is intended to elucidate on an interdisciplinary level those aspects of “Knowledge at Work”, which are expressed in the logical and philosophical foundations of science combining historical investigations, current theoretical research and methodological prognoses and prescriptions to its further development. In accordance with such an intention the speakers are encouraged in their papers (1) to use their scrutiny of the history of given field of science for elucidation of present theoretical activities (2) to apply the information about recent theoretical investigations – proper as well as of other scientists, for new interpretation of the historical development of corresponding problems and ideas in the past, (3) to make methodological conclusion from both the history of science and the recent theoretical investigations about the approach to further theoretical investigations in the given field of science or merely of given scientific problem outlining the perspectives of its further development. In the same time the participants of the Symposium are encouraged in their papers and discussions to follow the interdisciplinary approach, in particular to combine problems, ideas and methods of logic, philosophy of science, history of science, mathematics, natural sciences, technology and medicine, to pay attention to their common places. Correspondingly, the Symposium is intended in the course of presentation of papers and of their discussion to unify the efforts of specialists from different spheres of the human knowledge: (1*) historians of science, technology and medicine showing interest also (1*.1) to logical and philosophical aspects of their studies as well as (1*.2) to problems of the history of logical and philosophical foundations of respective field of science, technology, medicine; (2*) logicians and philosophers working on the foundations of sciences, technology, medicine, and in the same time paying attention to the historical aspects of their research; (3*) specialists of various fields of sciences, technology and medicine, paying attention to the logical, philosophical and historical aspects of their research; (4*) scholars working in the field of interdisciplinary problems.

The programme of present symposium naturally don’t exhaust its subject formulated above by means of its title. But its organisers hope the execution of this programme in the course of its work to be not merely one day event however an essential step in the process directed to more complete treatment of the given subject and they recommend the participants to have in mind this perspective during discussion of presented papers.
