A notable portion of Clark's research concerns the moral status of non-human animals. In his 1977 publication, The Moral Status of Animals, he explored the logical extension of liberal principles regarding unnecessary suffering and the implications for vegetarianism. He later examined the limits of animal morality in The Nature of the Beast (1982), positing that while animals exhibit certain behaviours, they lack the capacity for moral theorising. From 1998 to 2006, he served on the British government's Animal Procedures Committee, which advises on animal testing. He also participates as an advisory board member for the Christian Vegetarian Association.
Philosophical Focus on Plotinus
In more recent years, Clark has dedicated his scholarly output to the study of Plotinus. This work includes Plotinus: Myth, Metaphor and Philosophical Practice, released in 2016, and a translation with commentary of Ennead VI.9: On the Good or the One, published in 2020. His engagement with this period of ancient thought extended to the 2022 publication, Cities and Thrones and Powers: Towards a Plotinian Politics, further solidifying his focus on late antique philosophy and epistemology.
Lectures and External Appointments
Throughout his tenure, Clark delivered several invited lecture series at major universities. These included the 1981–1982 Gifford Lectures at the University of Glasgow, the Stanton Lectures at Cambridge between 1987 and 1989, and the Wilde Lectures at Oxford in 1990. He has also held visiting positions, including a tenure at Vanderbilt University and an Alan Richardson Fellowship at Durham University.
