From PKP's press release (which does not appear to be on-lline yet):

WASHINGTON, D.C. – Jonathan Schaffer and Jessica Wilson are the 2014 honorees of the Martin R. Lebowitz and Eve Lewellis Lebowitz Prizes for Philosophical Achievement and Contribution for their symposium titled “Grounding in Metaphysics.” 

The Lebowitz Prizes offer significant, tangible recognition for excellence in philosophical thought. An honorarium of $30,000 will be awarded to each winner. 

Both of the honorees are celebrated philosophers and published authors in the field.   Schaffer, a professor at Rutgers University, defends a distinctive posit of grounding as needed to characterize metaphysical dependence, while Wilson, an associate professor at the University of Toronto Scarborough, argues that ordinary metaphysical relations are better suited for this work.

As part of the award, Schaffer and Wilson will present their work highlighting contrasting viewpoints on grounding in metaphysics. Their symposium will take place at the Eastern Division American Philosophical Association meeting December 27-30 in Philadelphia, PA.  Awarded by the Phi Beta Kappa Society in conjunction with the American Philosophical Association, the Lebowitz Prizes are made possible by a generous bequest from Eve Lewellis Lebowitz, honoring her late husband, Martin R. Lebowitz.
