The Logic and Religion Webinar is a World Seminar Series organized by the Logic and Religion Association (LARA). It is an open platform for all scholars interested in the relationship between logic and religion, reason and faith, rational inquiry and divine revelation.

The sessions take place on Thursdays at 4pm CET (click here to convert to your timezone). They are held via Zoom and are free to attend.


Please register in advance!

Video recordings of the seminars are uploaded on the Logic and Religion YouTube channel.

Each webinar session is chaired by a scholar involved in LARA’s projects and features one or more speakers on a topic related to logic and religion. Sessions begin with a brief presentation by the chair, followed by a talk by the speaker(s) (approximately 40 min) and then a discussion (approximately 40 min).

Speaker: Graham Oppy (Monash University, Australia) 

ChairRicardo Silvestre (University of Campina Grande, Brazil)

In this webinar I discuss the following topics: (a) the concept of a god; (b) the concept of God; (c) conceptions of God; (d) the Simple Being; (e) the Greatest Being; and (f) the Perfect Being. I argue that, perhaps, we should think of the word 'god' as a family resemblance term; I suggest that, for some purposes, it is useful to stipulate that gods are venerable beings that have and exercise power over all else. I argue—in line with my book Describing Gods: An Investigation of Divine Attributes (pp. 1-22)—that, necessarily, something is God if and only if it is the one


and only god. I insist that this nominal definition does all of the work that we need nominal definitions to do. I suggest that we might extract real definitions of God from theistic theories about God. I then go on to discuss three different real definitions that some theists have given of God: 'the Simple Being', 'the Greatest Being', and 'The Perfect Being'. My discussion of the Greatest Being follows Jeff Speaks' book The Greatest Possible Being. My discussion of the Perfect Being criticises the line that Rasmussen takes in his review of Speaks' book. In addressing these topics, I hope to also address what might be called "the logic of the concept of God".

Speakers: Piergiorgio Odifreddi (University of Turin, Italy) and Jan Woleński (Jagiellonian University, Poland) 

ChairStanisław Krajewski (University of Warsaw, Poland)

What are the reasons for disbelieving in the existence of God? Do these reasons outweigh the reasons for believing in God as well as for suspending belief in God? What kind of arguments are there to support atheism? Do these arguments resist the peculiarities of the various religious traditions so as to make belief in any God (or, to be more precise, in the existence of any entity that falls under a concept of God) irrational? These are some of the questions that will be addressed in this session, which will be partially based on two works by the speakers: Caro Papa, ti scrivo (which was answered by the  Pope Benedict XVI in his Letter to Atheist) and Theism, Fideism, Atheism, Agnosticism.

Swinburne's reply to questions posed in the chat

Speaker: Richard Swinburne (University of Oxford, UK)

ChairDragana Jagušić (University of Rijeka, Croatia)

Are we our bodies? Or are we something beyond them, a metaphysical soul that is different from the body and that survives its death? In our next webinar, Richard Swinburne will deal with these issues as addressed in his most recent book: Are we Bodies or Souls? (OUP, 2019). More specifically, he will present the argument for the existence of the soul contained in chapter 3 and section A of chapter 4 of his book, which is basically the same as the argument contained in his article "Our souls make who we are" (Think, 57 : 53 -67, 2021).

What contribution can logic as an academic field provide to the philosophical reflection on God and religion? Could this contribution extend to other dimensions of the study of religion, such as the sociology and anthropology of religion? Can logic contribute to bringing religion closer to rationality? On the other hand, in what sense can religion bring new insights to the study and development of logic? Can we talk about Logic and Religion as a new field of research? If so, what is peculiar about this field that differentiates it from other areas of research, both in terms of methodology and object

of study?  Is it a multidisciplinary,  interdisciplinary or transdisciplinary research field? These are some of the questions that will be addressed in this opening session of the Logic and Religion Webinar. It will be facilitated by members of the LARA Boards and will have the participation of many of the academics who have been involved in LARA's conferences and publications. We hope to have a lively and exciting discussion.

Speaker: Laurent Lafforgue (Institut des Hautes Études Scientifiques, France) 

ChairSnezana Lawrence (Middlesex University, UK)

In a text of 1971 entitled The New Universal Church, the famous mathematician Alexander Grothendieck defended that through a process of imperialist expansion, science has created an ideology of its own, scientism, that has many of the features of a new religion. He called it "La nouvelle église universelle". How does Grothendieck's text against scientism and the imperialism of science relate to his thought? How does it relate to his mathematics as well as to his ideas about religions ? Can it be said that Grothendieck had become against science or that, in some sense, he had always been against some form of science? These are some of the questions that will be addressed in this webinar. 


Newton da Costa

September 16, 2021, 4pm CEST

Speakers: Newton da Costa (Federal University of Santa Catarina, Brazil), Jc Beall (University of Notre Dame, USA) and Paul Weingartner (University of Salzburg, Austria)

ChairJean-Yves Beziau (Federal University of Rio de Janeiro, Brazil)

Is the concept of God contradictory? But what a contradiction really is? Is it a basis or limitation of our thinking? Is the principle of non-contradiction a key to the understanding of reality? If it is, how can we use it properly? Can logical systems that relativize this principle, paraconsistent logics, as promoted by Newton da Costa, help us to clear the way and have a better understanding of God? These are some of the questions that will be addressed in this session, which will be  based on some recent works by the speakers: Is God Paraconsistent?The Contradictory Christ and Theodicy - From a Logical Point of View.
