ABSTRACT
It is very difficult to say how much of the whole Sceptic doctrine is due to its first representatives. For the only Scepticism about which we have abundant information is late Scepticism, and even there we know more of its history than of its tenets and arguments. But can it be proved that the essential part of these does not come from the tradition of the school? It is, therefore, safer, since we cannot discuss the evidence here, not to separate the two phases of Scepticism, so long as we remember that they are divided by about three centuries, and that the second phase is in part contemporary with the last period of the history of Greek thought.
