On Equilibrium is an intelligent, persuasive and controversial exploration of the essential qualities of humanity and how they can be used to achieve equilibrium for the self and to foster an ethical society. It is at once an attack on our weakness for ideologies and a manual for humanist action. It is the logical, compelling and humane successor to Saul's bestselling trilogy Voltaire's Bastards, The Doubter's Companion and The Unconscious Civilisation.
