 In his youth, Berlin’s intellectual development followed that of English-language philosophy; yet he drifted away from the analytic philosophy in which he had once been deeply involved, and his later writings are a world away from most Anglo-American philosophy of their time. On the other hand, for all his range of historical and cultural reference, and his concern with moral and aesthetic questions, and despite the influence of Kant and Kant’s successors on his thought, Berlin seems out of place in the world of Continental philosophy. Yet it would be a mistake to accept Berlin’s own judgement that he had departed from the realm of philosophy altogether. For both the views he had formed while working as a professional philosopher, and his tendency to connect political, historical and cultural issues to deeper moral and epistemological questions, set his work apart from that of other historians and ‘public intellectuals’ of his day.
