Ferdinand de Saussure's Course in General Linguistics was first published in 1916, three years after his death. The book aims to explain Saussure's theory that all languages share an underlying structure, and that this underlying structure is the same, regardless of historical or cultural context. Although the book marked a break with the traditional, history-focused study of linguistics of the time, Saussure still uses examples based on more traditional studies.
What is the nature of our personal relationship with God? That's the core question of Fear and Trembling. If God asks us to do something we instinctively feel is unethical, must we obey and have faith that he knows best?

His unique reading of the story breaks new ground, focusing on our relationship with God at an individual level.
Northern Irish academic, novelist, and broadcaster C. S.
