Pauline Phemister

This article examines the history of ideas during the early modern period. René Descartes extended the term idea to include sensation, imagination, and memory and located ideas in the human intellect. Not all philosophers agreed with him, and among the most prominent resistors were Baruch Spinoza and Nicolas Malebranche. Spinoza viewed ideas as modes of God insofar as God possesses the attribute of thought. Malebranche too insisted on retaining the pre-Cartesian opinion that ideas exist in God and not in human minds.

I have awaited Professor Kulstad’s new book since Philosophia first announced its forthcoming publication in 1989. The wait perhaps increased my expectations, but now, with book in hand, I am in no way disappointed. The book concerns Leibniz’s views on apperception, consciousness and reflection. These concepts play important roles in Leibniz’s metaphysics. Scholars on the continent at the turn of the century recognized this, but anglo-american Leibnizians generally did not, although recently the issues have attracted the attention of McRae, Jolley and Rescher.

In the present book, Pauline Phemister argues against traditional Anglo-American interpretations of Leibniz as an idealist who conceives ultimate reality as a plurality of mind-like immaterial beings and for whom physical bodies are ultimately unreal and our perceptions of them illusory. Re-reading the texts without the prior assumption of idealism allows the more material aspects of Leibniz's metaphysics to emerge. Leibniz is found to advance a synthesis of idealism and materialism. His ontology posits indivisible, living, animal-like corporeal substances as the real metaphysical constituents of the universe; his epistemology combines sense-experience and reason; and his ethics fuses confused perceptions and insensible appetites with distinct perceptions and rational choice. In the light of his sustained commitment to the reality of bodies, Phemister re-examines his dynamics, the doctrine of pre-established harmony and his views on freedom. The image of Leibniz as a rationalist philosopher who values activity and reason over passivity and sense-experience is replaced by the one of a philosopher who recognises that, in the created world, there can only be activity if there is also passivity; minds, souls and forms if there is also matter; good if there is evil; perfection if there is imperfection.

The work of seventeenth-century polymath Gottfried Wilhelm Leibniz has proved inspirational to philosophers and scientists alike. In this thought-provoking book, Pauline Phemister explores the ecological potential of Leibniz’s dynamic, pluralist, panpsychist, metaphysical system. She argues that Leibniz’s philosophy has a renewed relevance in the twenty-first century, particularly in relation to the environmental change and crises that threaten human and non-human life on earth. Drawing on Leibniz’s theory of soul-like, interconnected metaphysical entities he termed 'monads', Phemister explains how an individual’s true good is inextricably linked to the good of all. Phemister also finds in Leibniz’s works the rudiments of a theory of empathy and strategies for strengthening human feelings of compassion towards all living things. Leibniz and the Environment is essential reading for historians of philosophy and environmental philosophers, and will also be of interest to anyone seeking a metaphysical perspective from which to pursue environmental action and policy.
