We should follow, men say, the example of the bees, who flit about and cull the flowers that are suitable for producing honey, and then arrange and assort in their cells all that they have brought in. We too should so blend whatever we have gathered from a varied course of reading, that it may be all the clearer for being drawn from many sources; and then, by applying the supervising care with which our nature has endowed us, we should so blend those several flavors into one delicious compound that, even though it betrays its origin, yet it nevertheless is clearly a different thing from that whence it came.
