Stephen Trombley's Fifty Thinkers Who Shaped the Modern World traces the development of modern thought through a sequence of accessible profiles of the most influential thinkers in every domain of intellectual endeavour since 1789. No major representative of post-Enlightenment thought escapes Trombley's attention: the German idealists Kant, Fichte, Schelling and Hegel; the utilitarians Bentham and Mill; the transcendentalists Emerson and Thoreau; Kierkegaard and the existentialists; founders of new fields of inquiry such as Weber, Durkheim and C.S. Peirce; the analytic philosophers Russell, Moore, Whitehead and Wittgenstein; political leaders from Mohandas K. Gandhi to Adolf Hitler; and - last but not least - the four shapers-in-chief of our modern world: the philosopher, historian and political theorist Karl Marx; the naturalist Charles Darwin, proposer of the theory of evolution; Sigmund Freud, the father of psychoanalysis; and the theoretical physicist Albert Einstein, begetter of the special and general theories of relativity and founder of post-Newtonian physics.Fifty Thinkers Who Shaped the Modern World offers a crisp analysis of their key ideas, and in some cases a re-evaluation of their importance as we proceed into the 21st century.
