The article discusses knowledge and reality. In his most important book, “The Metaphysics,” Aristotle wrote that all men, by nature want to know. They want to know the world itself and know themselves. This knowledge is present in the whole of human history. Some thought about the world is present, some thought about man is present.

This article presents the works of great Polish philosopher, Mieczysław Albert Krąpiec, whose creative output can be applied to professional nursing practice. Krąpiec's philosophical heritage is extensive and encompasses many philosophical fields: metaphysics, philosophical anthropology, philosophy of law, philosophy of culture, philosophy of politics and philosophy of language. Krąpiec created an original philosophical synthesis characterized by a realistic approach. In this paper, I present only one of several original philosophical concepts developed by Krąpiec: the theory of the person based (...) on seven essential characteristics, that is the ability for cognition, love, freedom, religion, legal subjectivity, completeness and dignity. I attempt to show how these personal characteristics correspond to various patient needs. I argue that the qualitative deficit of any personal characteristics indicated by Krąpiec corresponds to a patient's real need that must be satisfied. I also stress that the skilful diagnosing of all—not only selected—qualitative deficits of characteristics can be defined as holistic care in the nursing profession. (shrink)
