What’s An Idea Versus What’s Real

The notion of reality is one of the most basic and most abstract ones we have. Raising questions about the very idea of what’s real has led to some of the most important, classic work in philosophy – from Parmenides to Aristotle to Avicenna to Aquinas to Immanuel Kant. It also, however, has a tendency to produce the kind of frustrating, easily caricatured work that leads people – including many philosophers – to wonder whether certain questions are simply pointless or even illegitimate, and to adopt a kind of skeptical stance towards abstract questions in general. – Aeon
