Love may be all around us, but it often seems more as if our conceptions of love are all over the place. In this intelligent and fascinating new book, released in time for St Valentine's Day, popular philosopher Mark Vernon argues that we have a tendency to approach questions about love as if there was a key to love that we must unlock. No more clearly is this shown than in our eagerness to learn about the science of love. Mark explores the ideas of neuroscientists and psychologists, who have become the modern-day oracles of love. But, he goes on, science is limited - we can learn more of love from Shakespeare than from Darwin.
