an interesting and careful book....In its care and philosophical sophistication, The Metaphysics of the Social World is worlds away from the old individualist debate....

The arguments are pleasingly analytic...Ruben's careful, patient analyses provide a substantial challenge to philosophers sympathetic to individualism.
Ruben's clear, careful and pointed arguments should disturb much dogmatic slumber....Ruben himself proceeds with clarity, caution and nuance...The corrective offered to the common casualness of individualists about their duties of argument is a model of analytical philosophy...I warmly applaud so sharp and courteous an exercise of analytical philosophy...Faced with thinking so distilled, subtle and precise, individualists will have to take the book seriously and will be hard put to reply.

This book is lucidly written, and packed with arguments set out with great care: in this respect the book is a model of analytic philosophy and it should be read by everyone interested in the philosophy of social sciences.
