The notion of otherness, often misused, requires important conceptualization work in order for it to be considered in all of its forms, and not simply reduced to the account of others. Although otherness certainly questions the link to the other (relation), it also questions the link to the self (reflexivity) and the link to knowledge (epistemology). Being tridimensional, the process of otherness is a paradox, the meaning of which can only be drawn thanks to ethics, psychoanalytical orientation and the history of philosophical ideas.

This book, which relates to philosophy of education, seeks to explain the problematic notion of otherness, the desire for which is specific to humankind. It examines how otherness questions the limits of knowledge, transmission and language, and argues that it is in fact a value, a tool and practice for all the actors involved in the relationship between education, knowledge and care.
