Abstract

In this study, it is tried to put forth some explanations on the definition of vitality referring to the historical definition of biology that can be considered as thestudy of life. In accordance with the explanations, the necessity of revision and distinction of some terms in the contemporary biology is also mentioned. The first among which is the updating of the term known as homeostasis into homeokinesis. For this reason, a number of propositions are emphasized in order to clarify the distinction of meaning. The following three questions were repeated in the process and structure of the article: 1) What is vitality? 2) Does it have any degrees or grades? 3) If so, what is the basic-vitality? In the search for an answer to these questions, different topics of biology are cited as references. At the same time, by claiming that vitality is an emergent process, it is proposed to follow the emergentist view, rather than the reductionist view on the statements of biological facts and phenomena. As a result, the cell level in the hierarchy of the biological organization is discussed first and a threefold-vitality view emergent in the levels of cell, organ and organism is put forth. Consciousness and memory are immanent in every level of the proposed threefold-vitality. Keywords: Life, Cell, Homeokinesis, Consciousness
