WebHe essentially argues that more than 1 timelike dimension would remove our ability to predict the future from the present. In math terms, more than one timelike dimension would render our differential equations ultrahyperbolic, and ultrahyperbolic PDEs are not well posed for initial data given along spacelike hypersurfaces.
