This book discusses ten philosophical perspectives, or worldviews, which present original ideas capable of evoking in us values that are guidelines for personal conduct. Harmonising knowledge, values and conduct maximises our personal power and thereby enables us to solve the practical and psychological problems of human existence, or overcome those that cannot be solved. The philosophers discussed in this book embody ideas of considerable fascination and force which can change our lives by penetrating the illusions of appearance and the delusions of common sense. As philosophy is thinking critically about thinking, it is a liberating activity because philosophers confront us with our prejudices and arouse our curiosity without satisfying it.hey show us what they were and how philosophy inspired them to live productive lives. They did not seek disciples but encouraged others to philosophise with them.
