I do not hesitate to read all the books I have named, and all good books, in translations. What is really best in any book is translatable—any real insight or broad human sentiment.
Emerson argues that the most important elements of a strong book can survive translation into another language. He places particular value on “real insight” and broad human feeling, suggesting that ideas and experiences of lasting significance are not confined to the precise wording of the original text.
Within Books, the statement supports Emerson’s wider argument for practical and selective reading. He does not require readers to master every original language before engaging with major works. His claim is deliberately broad, however: aspects such as rhythm, wordplay, tone and cultural associations may be altered or lost in translation. The quotation therefore expresses confidence that a work’s central thought and human significance can often cross linguistic boundaries, even when some features of its original form cannot be reproduced exactly.
