Attached is a link to my slides from a talk I presented at the Humanist Convention in April of 2017 (last week as at the time of posting). They summarise some of my recent thinking about metaphysical naturalism, an argument in defence of which constitutes the majority of the talk. I hope they may be of use and interest to some. Eventually I will get around to writing up my thoughts into a proper article, which I will post on my blog. I anticipate, however, that it will be significantly more technical than these slides, so these may make a good ‘first introduction’ to some of these issues for people with less philosophical background.
