With Capitalism being the most prominent economic system in the West, this thesis dives into the quest whether it is also the most efficient in satisfying the human need of self -realization. Applying Helmuth Pless ner' s perspective on the human condition presented in his book Die Stufen des Organischen und der Mensch, I affirm the claim of Capitalism being the most efficient system, while pointing out its twofold nature. After introducing Plessner's philosophical anthropology and the main concepts of Capitalism, I will delve into the identified ambiguity of Capitalism's effects on humankind. This philosophical reflection is divided into two parts: positive and negative effects of Capitalism. The positive ones I identified include the facilitation of Capitalism in increasing the human degree of artificiality, in following individualistic goals, in pushing technological advancement and innovation, and the support of political diversity and peace. The negative effects identified include Capitalism's utopian promise of self- fulfillment, its promotion of human boundlessness resulting in negative environmental and socioeconomic impacts, and its encouragement in developing dependence-creating technologies. I conclude that the ambiguity of Capitalism is a reflection of the ambiguous excentric creator, humanity.
