Gare is the son of Frank Gare ISO, former Commissioner for Native Welfare and Regional Director of Aboriginal Affairs in Western Australia, and Nene Gare, author of "The Fringe Dwellers" and other novels. Gare graduated from the University of Western Australia with a BA (Hons) in philosophy. He then wrote his PhD at Murdoch University in which he formed his metaphysical process view of the world. Soon after that, he won a Fulbright Fellowship to Boston University. Gare has taught at Murdoch University, University of Queensland, Curtin University and Swinburne University. 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".

Gare's work is mainly in environmental philosophy, philosophy of culture and process philosophy metaphysics. In 1983 with Robert Elliot he published Environmental Philosophy, one of the first anthologies in this field. In 1993 he published Nihilism Incorporated: European Civilization and Environmental Destruction and Beyond European Civilization: Marxism, Process Philosophy and the Environment, and then in 1995 he published Postmodernism and the Environmental Crisis. In these works he attempted to explain the ascendance, world domination and environmental destructiveness of European civilization, the failure of orthodox Marxism as practiced 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-Hegelian political philosophy and eco-Marxism. In 1996 he published Nihilism Inc.: Environmental Destruction and the Metaphysics of Sustainability. He has continued to develop the ideas expounded in these books in a range of journals, book chapters, conferences and conference proceedings.

In more recent work Gare has published in the fields of narratology, hermeneutics, semiotics, complexity theory and Christopher Alexander’s theories of architecture, and called for a revival of the Radical Enlightenment as the true heir of the Renaissance struggle for democracy and a new relationship between humanity and nature. More specifically, he has been concerned to develop more adequate theoretical foundations for human ecology to provide an alternative to economics as the core discipline for formulating public policy, and has been developing a form of retrospective path analysis as an alternative to cost-benefit analysis as a framework for formulating such policy.

A critical review of his work has been made from within the domain of process philosophy by McLaren.

He is the founder and a chief editor of the online journal " Cosmos and History: The Journal of Natural and Social Philosophy" (ISSN: 1832-9101) which is a peer-reviewed, open-access journal of natural and social philosophy. 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. Philosophy so conceived is not exclusively identified with the work of professional philosophers, and the journal welcomes contributions from philosophically oriented thinkers from all disciplines."
