Transhumanism has enormous effect on temporary philosophical thought by forcing philosophers to take on many intellectual challenges. Not only philosophers deal with transhumanism but also scientists who try to create technological solutions that enable implementation of transhumanistic ideas. The question is whether all these ideas will be realized. The purpose of the article is to show that not all transhumanist aspirations can be put into practice. The first reason is that transhumanism limits human’s understanding to the material dimension. While this (...) is understandable in the naturalistic paradigm, this approach is insufficient when it comes to all complexity of human being and for this reason tanshumanism represents too narrow a human’s understanding to be able to implement its all assumptions. The second reason is that to enable people to become posthumans the latest technologies would have to be available to everyone and this seems impossible. If so, such a situation will divide people into ordinary people and posthumans and this could lead to conflicts that transhumanists want to avoid after all. Finally, the body-mind problem is essentially limited to emergentism, which corresponds to the naturalistic paradigm. It seems, however, that without the concept of the soul it is impossible to understand who a man is, his/her identity and consciousness and this is crucial for mind uploading. (shrink)
