James Lenman responded to this philosopher's argument that naturalism leads to "a bleak normative nihilism" in the essay, "Naturalism Without Tears".  One text by this philosopher asserts that his "tunnel" example requires deontic reasoning while his "bridge" example requires non-deontic reasoning in a section on the trolley problem. He asks "Could It Be Rational to Cause Oneself to Act Irrationally?" in the section, "Self Defeating Theories" in his best-known book, which later asks "What Happens When I Divide?" in a section on identity not being important. He argued for optimizing decisions according to "Kantian rule consequentialism" in his Triple Theory.  This author of "Personal Identity" posited that it was better to have a larger population with extremely unhappy people - that is his Repugnant Conclusion, which is what he believes will result from strict utilitarianism.
