He currently holds the position of Associate Professor in the Faculty of Life and Social Sciences at Swinburne University of Technology in Melbourne, Australia.

In 2006 he was a Keynote Speaker to the 6th International Whitehead Conference at Salzburg University, Austria, delivering a paper entitled: "Reviving the Radical Enlightenment".

In these works he attempted to explain the ascendance, world domination and environmental destructiveness of European civilisation, the failure of orthodox Marxism as practised in the Soviet Union and Eastern Europe to provide a real alternative to this, and the ineffectuality of deconstructive postmodernism in the face of the ecological crisis confronting humanity, while offering a different path into the future based on a synthesis of process metaphysics, neo-Aristotelian ethics, neo-Hegelian political philosophy and eco-Marxism, attempting to overcome the opposition between science and the humanities.

In more recent work Gare has published in the fields of narratology, hermeneutics, semiotics, complexity theory, theoretical biology, human ecology and philosophical anthropology, Schelling's philosophy, Chinese philosophy and Christopher Alexander's theories of architecture, biomathematics and biosemiotics, and called for a revival of the Radical Enlightenment as the true heir of the Renaissance struggle for democracy and for the creation of an ecological civilisation as a new world order based on a new relationship between humanity and nature.

Quoting the journal: "It serves those who see philosophy's vocation in questioning and challenging prevailing assumptions about ourselves and our place in the world, developing new ways of thinking about physical existence, life, humanity and society, so helping to create the future insofar as thought affects the issue.
