It might reasonably be argued that this question is one of those historical problems which form excellent subjects for the writing of essays, but which are far too complex to admit of a decisive answer, and consequently are much better left alone. No one man is responsible for a war between great powers, and the motives which influence the vast number of people, whose consent is necessary, can rarely, if ever, be identical. It is therefore comparatively easy to argue against (...) any given motive which is asserted to be the one and only reason. Certainly the writer would make no effort to rake up the ashes of this controversy, were it not that in Dr. Grundy's recent work on Thucydides a new and ingenious theory is put forward concerning the vera causa of the Peloponnesian War.
