There he tackles issues like medical ethics (beginning of life and end of life decisions), business ethics, environmental ethics (ethics of animal food production), the just the relationship between religion and culture in general, and so on… He has translated and published a slew of brilliant books and essays (from Dutch to English)… Cornelis Vonk, Abraham Kuyper, Herman Bavinck, so on.
