Is logic useful for doing Philosophy?

Providing some basic arguments and a historical context, I introduce the special volume What can we do in Philosophy using Logic? In this introduction, I discuss whether logic is useful for understanding, evaluating or building arguments in philosophy. I argue that, although there has been research supporting the idea that logic can serve as a philosophical instrument, this has not shown completely its utility. This is the reason I offer to discuss the importance of logic in philosophy, trying to show that philosophers employ logic when they work with arguments and also obtain worth benefits by applying it.
