Biology of scientific explanations and reflections on love. Any attempt of explanation and scientific argument has some validity if connected with a trace of objective reality. There is a recursive relationship between science and everyday actions and an observing can not exist without an observer. In this perspective, in which human systems can interact with each other recursively, love (spontaneous dynamic acceptance of the Other) is the source and sustenance of human socialization and not reductively, an effect.
Keywords: Other, love, complexity, knowledge, observer, to observe, human system, solidarity.
