Driven by a profound love of shapes and symmetries, Donald Coxeter (1907–2003) preserved the tradition of classical geometry when it was under attack by influential mathematicians who promoted a more algebraic and austere approach.
His essential contributions include the famed Coxeter groups and Coxeter diagrams, tools developed through his deep understanding of mathematical symmetry.
“Freedom from Fear” offers a striking new account of the dominant political and social theory of our time: liberalism. In a pathbreaking reframing of the historical debate, Alan Kahan charts the development of Western liberalism from the late eighteenth century to the present.
Examining key liberal thinkers and issues, Kahan shows how liberalism is both a response to fear and a source of hope: the search for a world in which no one need be afraid.
