Contemporary metaphysicians, whether they are aware of it or not, whether they credit their predecessors or not, frequently end up importing very problematic assumptions from historical debates previously enacted. Unless such assumptions are properly explored and questioned, we cannot feel confident that we are making any genuine progress in contemporary metaphysics rather than just repeating the same mistakes of our philosophical forebears. It is within this context that I find the work of historically minded philosophers to be particularly important. One such philosopher is Fraser MacBride.... an untold and surprising history of how the categories of particulars and universals have been understood in the history of early analytic philosophy
