  Sylvan’s motivations for developing plurallism are not uniquely philosophical. On the contrary, he believes that the existence of the plurality of actual worlds can have important political consequences too. One of those consequences is the extension and strengthening of our idea of tolerance. According to Sylvan, intolerant behaviours are often, if not always, grounded on ideologies driven by what he calls the “one-true-way” (1997, 462) or the “one-admissible-way” (1997, 462). Governments, religious groups, and even scientists believe that “truth should be imposed” (1997, 462) where truth is what is uniquely determined by them. Plurallism invites us to entertain the idea that, as there is no such thing as a unique actual world, there is no such thing as a unique truth. And this should undermine the ideological roots of intolerant behaviours.
