Bertrand Russell states that.
One defect, however, does seem inherent in a purely classical education--namely, a too exclusive emphasis on the past (para. 5).
He goes on to explain that looking only toward the past blinds us to the present and the possibilities of the future. What we see in the past is refined or perfected, but the present can be raw and unattractive, and looking at the past does not necessarily help us to see what is around us or to imagine what might be. He points out that as we view the past, what we do not see is that the beauty and richness came out of the same raw and unattractive state, something that is often not addressed. This leaves us with misperceptions about our own times and a failure of imagination about the future.
