Benedictus de Spinoza 
Ethics 

Ethics is a philosophical book written by Benedictus de Spinoza. Although published after Spinoza’s death, in 1677, it is considered his greatest and most famous work. In it, Spinoza tries to set out a ‘fully cohesive philosophical system that strives to provide a coherent picture of reality and to comprehend the meaning of an ethical life. Following a logical step-by-step format, it defines in turn the nature of God, the mind, human bondage to the emotions, and the power of understanding — moving from a consideration of the eternal, to speculate upon humanity’s place in the natural order, freedom, and the path to attainable happiness.’
