问答题

A good book is often the best urn (翁) of a life enshrining the best that life could think out; for the world of a man’s life is, for the most part, but the world of his thoughts. Thus the best books are treasuries of good words, the golden thoughts, which, remembered and cherished, become our constant companions and comforters. "They are never alone," said Sir Philip Sidney, "that are accompanied by noble thoughts. " Books introduce us into the best society ; they bring us into the presence of the greatest minds that have ever lived. We hear what they said and did; we see them as if they were really alive ; we sympathize with them, enjoy with them, grieve with them; their experience becomes ours, and we feel as if we were in a measure actors with them in the scenes which they describe. The great and good do not die even in this world. Embalmed in books, their spirits walk abroad. The book is a living voice. It is an intellect to which one still listens.
