Transhumanism (sometimes symbolized by >H or H+), a term often used as a synonym for "human enhancement", is an international, intellectual and cultural movement supporting the use of science and technology to enhance human mental, physical abilities and aptitudes, and overcome what it regards as undesirable and unnecessary aspects of the human condition, such as disability, suffering, disease, aging, and involuntary death. Transhumanist thinkers study the possibilities and consequences of developing and using human enhancement techniques and other emerging technologies for these purposes. Possible dangers, as well as benefits, of powerful new technologies that might radically change the conditions of human life are also of concern to the transhumanist movement.
