QUOTE : (...) one should never be too naive regarding the quality of the current philosophical culture, or imagine that the most recent thinking is in any meaningful sense more advanced or more authoritative than that of a century or a millennium or two millennia ago. There are certain perennial problems to which all interesting philosophy returns again and again; but there are no such things as logical discoveries that consign any of the older answers to obsolescence. Certain classical answers to those problems endure and recur, sometimes because they remain far more powerful than the answers (or evasions) produced by later schools of thought. And, conversely, weaker answers often enjoy greater favor than their rivals simply because they are in keeping with the prejudices of the age.
