Are women philosophers more insightful than their male counterparts?

I don't think that there's any special reason to think that female philosophers are more insightful than male philosophers -- or vice versa, for that matter. Nonetheless, it may be true that female philosophers on occasion have different insights from their male counterparts. For example, feminist critiques of traditional ethical theories (like those offered by Kant and Mill) suggest that those theories focus on masculine values and ignore values that are of fundamental importance to women. Feminist philosophers have worked to develop an "ethics of care" that looks at moral questions very differently from traditional theories.
