The essays are uniformly thoughtful, careful, and interesting … This collection demonstrates that new avenues of approach can point the way to new insights into philosophical concepts, they can help adjudicate between competing theories, and they can show how various subsets of the population make sense of ideas philosophers and mathematicians take for granted.

A team of leading figures and a new generation of scholars from experimental philosophy and the fields of philosophy of logic and mathematics examine the importance of empirical work to their disciplines.

Series Editor: Justin Sytsma is Associate Professor of Philosophy at Victoria University of Wellington, New Zealand. Empirical and experimental philosophy is generating tremendous excitement, producing unexpected results that are challenging traditional philosophical methods. Advances in Experimental Philosophy responds to this trend, bringing together some of the most exciting voices in the field to understand the approach and measure its impact in contemporary philosophy. The result is a series that captures past and present developments and anticipates future research directions.
