My research addresses questions at the intersection of ethics and cognitive science, in an effort to understand the development, breakdown, and improvement of moral knowledge and virtue.
I focus both on contemporary moral issues (e.g., animal welfare, moral enhancement, charitable giving) and more ordinary interactions with others (e.g., dishonesty, egoism). Based on an adequate understanding of the sources of our beliefs and decisions (our moral psychology and neurobiology), we can assess whether we’re justified in holding particular moral views and properly motivated to do what’s right. Against a rising pessimism, I’ve argued that moral thought and action are ultimately rational enterprises. (My views are thus largely “rationalist” and “non-skeptical.”) Nevertheless, there is certainly room for improvement, and my work also attempts to understand social change and moral progress. How, in particular, can the sciences of the mind help us to become more virtuous and better equipped to tackle societal challenges of the 21st century, such as factory farming, climate change, and mental illness?
