For he who for the sake of his comfort shrinks from war is likely, should he remain tranquil, very speedily to forfeit the delights of ease which caused him to shrink; and he who presumes upon his success in war has failed to reflect how treacherous is the confidence which elates him.
For many enterprises which were ill-planned have succeeded because the adversary has proved to be still worse advised, and yet more, which to all appearances were well advised, have turned out the opposite way and brought disgrace. For no one ever carries out a plan with the same confidence with which he conceives it; on the contrary we form our fond schemes with a feeling of security, but when it comes to their execution, we are possessed by fear and fall short of success.
" And so now in our own case, it is because we are suffering wrongs and have ample grounds for complaint that we are stirring up this war, and as soon as we have avenged our wrongs upon the Athenians we will bring the war to an end when occasion offers.
And for many reasons we are likely to prevail: first, because we are superior in point of numbers and in military experience ;
secondly, because we all with one accord obey the word of command; and, thirdly, on the sea, where their strength lies, we shall be able to equip a fleet, not only with the means which we severally possess, but also with the funds stored up at Delphi and Olympia.[*](cf. Thuc. 2.13.4, where Pericles suggests a similar resource. The Delphic oracle favoured the Peloponnesians, according to 1.118.3.)For by contracting a loan we can use the inducement of higher pay to entice away from them their mercenary sailors; for the forces of the Athenians are made up of hirelings rather than of their own citizens, whereas ours, whose strength lies more in the quality of the men than in the pay they get, would be less subject to such defection.
