“
Philosophy needs vision and argument… there is something disappointing about a philosophical work that contains arguments, however good, which are not inspired by some genuine vision, and something disappointing about a philosophical work that contains a vision, however inspiring, which is unsupported by arguments…Speculation about how things hang together requires… the ability to draw out conceptual distinctions and connections, and the ability to argue… But speculative views, however interesting or well supported by arguments or insightful, are not all we need. We also need what [the philosopher Myles] Burnyeat called ‘vision’ – and I take that to mean vision as to how to live our lives, and how to order our societies.
