"At point of death men often prophesy. My prophecy to you, my slayers, is that when I am gone you will have to face a far more serious penalty than mine. You have killed me because you wish to avoid giving an account of your lives. After me will come more accusers of you and more severe. You cannot stop criticism except by reforming yourselves. If death is a sleep, then to me it is gain; if in the next world a man is delivered from unjust judges and there meets with true judges, the journey is worth while. There will be found all the heroes of old, slain by wicked sentences; them I shall meet and compare my agonies with theirs. Best of all, I shall be able to carry out my search into true and false knowledge and shall find out the wise and the unwise. No evil can happen to a virtuous man in life or in death. If my sons when they grow up care about riches more than virtue, rebuke them for thinking they are something when they are naught. My time has come; we must separate. I go to death, you to life; which of the two is better only God knows." Two lessons of supreme importance are to be learned from Plato. In the first place he insists on credentials from the accepted teachers of a nation. On examination most of them, like Gorgias, would be found incapable of defining the subjects for the teaching of which they receive money. The sole hope of a country is Education, for it alone can deliver from ignorance, a slavery worse than death; the uneducated person is the dupe of his own passions or prejudices and is the plaything of the horde of impostors who beg for his vote at elections or stampede him into strikes. Again, the possibility of knowledge depends upon accurate definition and the scientific comparisons of instances. These involve long and fatiguing thought and very often the reward is scanty enough; no conclusion is possible sometimes except that it is clear what a thing cannot be. The human intelligence has learned a most valuable lesson when it has recognised its own impotence at the outset of an inquiry and its own limitations at the end thereof. Knowledge, Good, Justice, Immortality are conceptions so mighty that our tiny minds have no compasses to set upon them. Better far a distrust in ourselves than the somewhat impudent and undoubtedly insistent claim to certitude advanced by the materialistic apostles of modern non-humanitarianism. When questioned about the ultimates all human knowledge must admit that it hangs upon the slender thread of a theory or postulate. The student of philosophy is more honest than others; he has the candour to confess the assumptions he makes before he tries to think at all.
