Stanley Tweyman on “What is Philosophy of Religion?”, part 1


Stanley Tweyman

Stanley Tweyman is Professor of Philosophy at York University, Canada. We invited him to answer the question “What is Philosophy of Religion?” as part of our “Philosophers of Religion on Philosophy of Religion” series.

Philosophers have traditionally held that there are three ways to attempt to gain knowledge of God – through revelation, through reason (e.g. the Ontological Proof), and through Nature (e.g. through Natural Religion).In this essay, I want to point to a fourth way, which has not been widely recognized, namely, the proof put forth by Rene Descartes in his third meditation.[1]

In the Replies to the Second Set of Objections, Descartes informs us that the aim of his Meditations on First Philosophy is to provide the first principles of human knowledge, i.e. what must be known before anything else can be known. Because these principles are first principles, they cannot be established deductively, but rather they are self-evident, and must, therefore, be grasped through intuition. In the Replies to the Second Set of Objections and elsewhere, Descartes urges that there are two requirements in order to enable us to intuit these first principles – the first is the removal of all sensory prejudice (the influence of the senses), and the second is that we give full attention to what Descartes has written in his Meditations to guide us to the relevant innate ideas, through which these first principles can be intuited. In his third meditation, Descartes maintains that before anything can be known, he must know that God created his mind, and that God is not a deceiver. Given that, at this stage, he does not know anything beyond his existence as a thinking thing, Descartes attempts to establish what he needs to know about God through the innate idea he has of God.

Donald Blakeley is Emeritus Professor of Philosophy at California State University, Fresno. We invited him to answer the question “What is Philosophy of Religion?” as part of our “Philosophers of Religion on Philosophy of Religion” series.

The question “What is philosophy of religion?” invites reflection on the nature of philosophy as well as religion. I will suppose that philosophy includes analytic concerns (logic, conceptual analysis, functions of language) and constructive (speculative, systematic) concerns (metaphysics, epistemology, value theory). The two have been combined historically, although the speculative part has for some time come under criticism for attempting to deal with matters best handled by scientific disciplines.

Felix Ó Murchadha is Senior Lecturer in Philosophy at the National University of Ireland, Galway. We invited him to answer the question “What is Philosophy of Religion?” as part of our “Philosophers of Religion on Philosophy of Religion” series.

Any answer to the question, what is the philosophy of religion, will depend implicitly at least on how philosophy is understood. To me philosophy is the radical questioning of everything, including and especially itself. To practice philosophy is to be uncertain whether one is actually doing philosophy at all. This is a highly paradoxical situation to be in! With respect to religion what this means is that a philosopher does not come with a ready-made tool kit to investigate religion, anymore than she does with respect to art, science or anything else. The philosophical engagement with religion is one which seeks to allow religion to speak to it, in a manner which is challenging and fruitful – but challenging and fruitful to philosophy not to religion. As a philosopher I don’t see myself as having any responsibilities to religious people or communities, neither in the sense of respecting their sensibilities nor in the sense of critically challenging them. So philosophy of religion is in that sense not about religion at all, it is about what if anything religion can tell us or challenge us regarding the practice of philosophy.
