The purpose of this essay is to discuss the relationship of history and political science within the broader fields of the humanities and the social sciences. It will also discuss the nature of the humanities and of the social sciences.
The study of the humanities goes back to the foundation of the European universities in the twelfth and thirteenth centuries. The discipline, growing essentially out of the revival of classical studies that set off the Renaissance in Italy, was called the humanities because it dealt primarily with human values, rather than primarily with theology, and hoped to elucidate human nature rather than the nature of the divine. Human values and human nature were understood largely in religious terms in that period, of course, but given the Renaissance interest in re-appropriating and revaluing the classical world, the scope of the humanities included more than the strict Christianity of the early Middle Ages.
From that origin, the humanities have retained their earmark characteristic of being primarily concerned with the study and understanding of human values, however these might be expressed in a specific field. It is understood that a value is not a fact, but always something more like an a priori assumption. It is a given, not a conclusion, and cannot be objectively observed. It does not exist independently of the humans beings who hold it.
