Professor David Benatar, head of UCT's Department of Philosophy, considers what philosophy might contribute to how people can live a 'good' life.

Philosophy is a discipline with wide-ranging subject matter, and only some fields of philosophical inquiry - most obviously moral philosophy, but also related areas such as social and political philosophy - are directly concerned with questions about the good life. Philosophers hold a wide range of views, and thus philosophy does not offer a single answer.

Instead, philosophy, or at least analytic philosophy, offers a methodology for grappling with questions about the good life. This involves analysing - getting clear on what we mean by key terms and claims; drawing on empirical evidence; testing evaluative claims in various ways, including for consistency; and constructing logical arguments.

The evidence and arguments should - although unfortunately, they often do not - precede the conclusion. In other words, one should see where the evidence and arguments lead, rather than pick and choose evidence and arguments to fit some preconceived conclusion.

The sort of methodology described here is also used by those working on questions in other areas of philosophy, including metaphysics, epistemology, and the philosophy of language. At least some people believe that honing the relevant skills and gaining understanding can be one component of a good life.

It should be said that not all philosophical views about the good life are uplifting. Some philosophers think that while some lives can be better than others, no life can be really good.

That view is obviously contested, but it cannot be rejected merely because it is unpalatable. This is because one unfortunate fact about the world is that what is true is not always nice, and what is nice is not always true.

Even when it is not nice, however, the truth is at least sometimes worth having.
