Answer: INTERSUBJECTIVITY
Explanation: Intersubjectivity is a term originally coined by the philosopher Edmund Husserl (1859–1938), It is a kind of relationship which is considered a subject-to-subject or person-to-person way of relating.
It refers to a condition of a human being,a subject among other human beings who are also subjects fundamentally involved in a always meaningful engagement without reality with others.It was propound by social scientists as a short-hand description for a variety of human interactions.For example, self-presentation, lying, practical jokes, and social emotions all entail not a shared definition of the situation but partially shared divergences of meaning.
Intersubjectivity is considered as a crucial subject in communication not only at the relational level but also at the study of the nature of knowledge, justification, and the rationality of belief and even the fundamental nature of reality, including the relationship between mind and matter, between substance and attribute, and between potentiality and actuality. For example, intersubjectivity is postulated as playing a role in establishing the truth of propositions, and constituting the so-called objectivity of objects.
