There is one book which is open to every one—the book of nature. In this good and great volume I learn to serve and adore its Author. There is no excuse for not reading this book, for it speaks to all in a language they can understand.

Context

“I call to witness the God of Peace whom I adore, and whom I proclaim to you, that my inquiries were honestly made; but when I discovered that they were and always would be unsuccessful, and that I was embarked upon a boundless ocean, I turned back, and restricted my faith within the limits of my primitive ideas. I could never convince myself that God would require such learning of me under pain of hell. So I closed all my books. There is one book which is open to every one—the book of nature. In this good and great volume I learn to serve and adore its Author. There is no excuse for not reading this book, for it speaks to all in a language they can understand. Suppose I had been born in a desert island, suppose I had never seen any man but myself, suppose I had never heard what took place in olden days in a remote corner of the world; yet if I use my reason, if I cultivate it, if I employ rightly the innate faculties which God bestows upon me, I shall learn by myself to know and love him, to love his works, to will what he wills, and to fulfil all my duties upon earth, that I may do his pleasure.” source
