Anti-perfectionism is a philosophical perspective combining the view of man as an imperfect and non-self-sufficient being with a scientific epistemology based on imperfect knowledge. From an epistemological perspective, it has roots in Socrates and, more recently, in the post-empiricism of Giambattista Vico, up to phenomenology. From an anthropological perspective, it is a philosophical tradition based on an awareness of the constitutive dependency of individual performance and fulfilment of man on his interaction with others. It is conceived in opposition to the individualism and perfect rationality of most social theories. The paper analyses both the philosophical and the epistemological premises of anti-perfectionism as well as its consequences in terms of economic methodology. It will specifically develop the momentary intersection of phenomenology and Austrian economics. The theory of knowledge and of sense-making of phenomenology will be discussed with particular attention to intersubjectivity, which expresses anti-perfectionism well. The interpretations of human knowledge and action of Scheler and Schütz are analysed and connected to some contemporary streams of Austrian economics.
