And all this was not on any special occasion, or when his administration was especially popular, but for forty years he held the first place among such men as Ephialtes, Leokrates, Myronides, Kimon, Tolmides, and Thucydides; and, after the fall and banishment of Thucydides by ostracism, he united in himself for five-and-twenty years all the various offices of state, which were supposed to last only for one year; and yet during the whole of that period proved himself incorruptible by bribes. As to his paternal estate, he was loth to lose it, and still more to be troubled with the management of it; consequently, he adopted what seemed to him the simplest and most exact method of dealing with it. Every year's produce was sold all together, and with the money thus obtained, he would buy what was necessary for his household in the market, and thus regulate his expenditure. This did not make him popular with his sons when they grew up; nor yet did the women of his family think him a liberal manager, but blamed his exact regulation of his daily expenses, which allowed none of the superfluities common in great and wealthy households, but which made the debit and credit exactly balance each other. One servant, Euangelos, kept all his accounts, as no one else had either capacity or education enough to be able to do so. These proceedings differed greatly from those of Anaxagoras the philosopher, who left his house, and let his estate go to ruin, while he pursued his lofty speculations. I conceive, however, that the life of a philosopher and that of a practical politician are not the same, as the one directs his thoughts to abstract ideas, while the other devotes his genius to supplying the real wants of mankind, and in some cases finds wealth not only necessary, but most valuable to him, as indeed it was to Perikles, who assisted many of the poorer citizens. It is said that, as Perikles was engaged in public affairs, Anaxagoras, who was now an old man and in want, covered his head with his robe, and determined to starve himself to death; but when Perikles heard of this, he at once ran to him, and besought him to live, lamenting, not Anaxagoras's fate, but his own, if he should lose so valuable a political adviser. Then Anaxagoras uncovered his head, and said to him, "Perikles, those who want to use a lamp supply it with oil."
