Aristotle was one of the greatest philosophers that has ever lived. Taught by Plato, he was the first genuine scientist in history, a true pioneer of both science and philosophy. Widely credited as the inventor of the field of formal logic, his ideas have remained relevant throughout the world down through the centuries. Whilst little is known about his life, he tutored Alexander the Great and established a library in the Lyceum. The poet Dante called him ‘the master of those who know’. Kenneth Mcleish’s short work is the perfect introduction to one of the most influential philosophers and scientists of all time.
