This volume investigates the fundamental relationship between the human capacity for conceivability and the metaphysical status of possibility. Editors Tamar Szabó Gendler and John P. Hawthorne assemble a collection of essays from leading philosophers to examine how mental representation informs our understanding of what can exist. The work addresses whether the ability to imagine a scenario serves as a reliable guide to objective reality or if it remains a purely psychological phenomenon.

Experts recognize this collection as a significant contribution to contemporary analytic philosophy, particularly within the study of modality. Readers frequently note the academic density of the prose, which is intended for advanced students and professional philosophers engaged in metaphysical research.
