According to the received opinion there is a theoretical incompatibility between Herbert Hart's The Concept of Law and Alf Ross's On Law and Justice, and, according to the received opinion, it stems above all from Hart's emphasis on the internal point of view. The present paper argues that this reading is mistaken. The Concept of Law does not go beyond On Law and Justice in so far as both present arguments to the effect that law is based on a shared (...) understanding between participants in a project perceived by every participant to be a project in common. The paper demonstrates that there are substantive parallels between Hart's combination of “acceptance” or “acknowledgement” and a “critical reflective attitude” and Ross's combination of “motivation” or “feeling” and a “coherent whole of meaning and motivation.” The main conclusion is that the views of norms and normativity put forward in The Concept of Law and On Law and Justice are very close in essential respects, and, more specifically, that the two works are at root identical in their representation of the basis of normativity in reality.

The separability thesis claims that the concept of law can be explicated independently of morality, the normativity thesis, that it can be explicated independently of fact. Continental normativism, prominent above all in the work of Hans Kelsen, may be characterized in terms of the coupling of these theses. Like Kelsen, H. L. A. Hart is a proponent of the separability thesis. And–a leitmotiv–both theorists reject reductive legal positivism. They do not, however, reject it for the same reasons. Kelsen's reason, in (...) a word, is the normativity thesis. Hart, however, grounds his theory in social fact. In place of the reductive thesis of the legal positivist tradition, and in sharp contrast to Kelsen's normativity thesis, Hart defends a non‐reductive version of what the author terms the facticity thesis.
