See my review for - "transformations" and perhaps some of the points raised in the book "The Brain & the meaning of life" can be discussed.
1. Can the meaning of life be relatedness, autonomy & competence (abstractions) instantiated in terms of the practical actions of love, work & play ?
2. Are "psychological needs" such as autonomy, relatedness, competence objective, can they be objective ? How could we know ? How could we make a standard ? Test this ? Is it just an assertion based on the writers preferance ?
3. Can naturalism be harmonized with an objective ethics/morality ? (defended against relativism and Niestzchian Nihillism)
4. Other thoughts on the book by P.Thagard or similar books/recommendations
