One generation abandons the enterprises of another like stranded vessels.

Human thought has no limit. At its risk and peril, it analyses and dissects its own fascination. We could almost say that, by a sort of splendid reaction, it fascinates nature; the mysterious world which surrounds us returns what it receives; it is probable that the contemplators are contemplated.

Set not thy foot to make the blind to fall;
  Nor wilfully offend thy weaker brother:
  Nor wound the dead with thy tongue’s bitter gall,
  Nor rejoice thou upon the fall of other.
