A general, accessible, but at times detailed, introduction of key domains of philosophy: epistemology, morality and ethics, metaphysics, and logic. Never labouring the point, Picard's colourful and well-explained introduction is a perfect early read before delving into a set of more comprehensive works like: Russel's The History of Western Philosophy if you like a biographic-driven understanding of philosophy; or the primary texts themselves - the Greeks are easier to read than you may suspect.
