Abstract

Klemens Szaniawski, who is associated with the philosophy of science and logic, in his deliberations is also dealing with decision theory and indicates to its connections with ethic. Starting from conceptual and linguistic links between decision theory and ethics, Szaniawski is looking for their further connection.
    In the article various applications of decision theory are exhibited in relation to shaping the personality of a man. Firstly, it is noted that the concept of “rationality” is this element which bind ethic with the decision-making process.
    Secondly, a decision contains two elements: the choice of action and its implementation. The decision is relative to an objective, and the objective determines the aggregation, and the selection takes into account the beliefs and values of decision-maker. Thirdly, to understand the concept of decision, it should be associated with a person who has a character and it is molded during making decisions. Moreover, in the specific decisions of the person appear objectives, capabilities and motives. Therefore, the inclusion of decision theory to analyze the personality of the person and defining identity allows for multi-sided human knowledge.
    The new look at the issue of the whole decision-making process, indicated the possibility of a pragmatic application of the concepts of decision theory in ethics. To determine the suitability of conceptual apparatus decision theory in practice, illustrative examples drawn from science: law and medicine.
