David Hume, The Natural History Of Religion - The Development Of Polytheism
This lecture discusses key ideas from the 18th century philosopher and essayist David Hume's essay The Natural History Of Religion.
It focuses specifically on the development of what he classifies as "polytheism" (contrasting that with "theism", i.e. monotheism). Hume provides an account that views all of the ancient and contemporary polytheistic religions as derived from natural psychological processes of human beings, developed within their cultures.

Jeremy Bentham, Introduction to Principles - Utilitarianism And The Hedonic Calculus
This lecture discusses key ideas from the Utilitarian philosopher, Jeremy Bentham's work, Introduction to the Principles of Morals and Legislation
Here we examine his discussion of what he calls the "hedonic calculus", which is how a utilitarian applies the principle of utility in practice for moral decision-making. We look at each of the seven factors Bentham includes in this calculus, and apply them to some everyday examples.

A Perfectly Simple God and Our Complicated Lives - The 2008 St. Anselm Lecture, part 3
This is part 3 of the the recording of my invited Saint Anselm Lecture, given in 2008 at Saint Anselm College. Here is the abstract of the paper:
One important divine attribute Saint Anselm examines and treats is that of simplicity. His treatment brings out some surprising features of simplicity itself which escape the frameworks of the logic of created being, providing us a fuller, albeit still very partial, understanding of the true nature of that attribute. A deep problem can then arise for the created human being in the course of such speculations and investigations: How can a complex, complicated, composite created being more closely approach a perfectly simple divine being? In both our thought and in our practice, it seems that our attempts to approach God simply introduce even more complexity into things. My paper addresses that problem. The first section of the paper presents five short Anselmian lessons about the divine attribute of simplicity. The second section then frames and explores the problem. The third and final section provides an Anselmian resolution to the problem.

Alasdair MacIntyre, After Virtue - Emotivism as a Moral Theory - Sadler's Lectures
This lecture discusses key ideas from the 20th and 21st century philosopher and moral theorist, Alasdair MacIntyre's work After Virtue
It focuses upon chapter 3, specifically on his discussion of MacIntyre's analysis of the key and distinctive aspects of Emotivism as a moral theory. Emotivism was presented originally as a meta-ethical theory, but as MacIntyre notes, it develops into its own ethical stance that rules out the possibility of rational inquiry into and agreement upon moral matters.
