The complex thought understands the ethics not only as the moral respect to the other and to the environment. It sees it as a construction between the antagonisms of human nature. The objective of this research has focused on verification on how occurs the relationship with the other in the practice of climbing in school. The method based on Qualitative Epistemology allowed confronting elementary school students with the ethics of climbing. The results point to the development of a sense of responsibility to life, not common in traditional education. The values of human dignity, solidarity and risk taking in the adventure were assimilated by the students, by binding to the other by a rope, feeling the fragility of life in their hands. This experience points to new ways for citizenship education, based on human ethics.
