audacious words: “I would rather stand thrice in the line of battle than bear a child once.” If we had to sum up the new characteristic of the fourth century under a single phrase, we should perhaps be justified in saying that the professional spirit was making itself felt in all directions. We see it in the military art, where the citizen hoplites, with their extremely simple tactics and strategy, are yielding to trained bands under professional captains. The statesmen are now no longer the famous generals of the day, nor men marked out by birth and wealth for high position, but trained speakers, and often professional pleaders. Literature is no longer in the hands of men like Æschylus and Sophocles, who were soldiers or generals as well, though Xenophon is of course a notable example of the writer who takes literature among his other activities. But now there are professional sophists teaching oratory and various literary arts. Books circulate freely, schools of professional philosophers arise, as in Plato’s garden of the Academy. This specialisation naturally involves an increased attention to technical processes, a more scientific and less human outlook, and a growth of self-consciousness. For example, it is now that constitutional histories begin to be written. While people are young and [Illustration: PLATE LXVIII. MELEAGER: HEAD AFTER SCOPAS _Anderson_] strong they are apt to take their constitutions for granted. Greece is now grown to full stature, and beginning to grow introspective and emotional.
