Letters 40.11

However, I suppose that certain styles of speech are more or less suitable to nations also; in a Greek you can put up with the unrestrained style, but we Romans, even when writing, have become accustomed to separate our words. And our compatriot Cicero, with whom Roman oratory sprang into prominence, was also a slow pacer. The Roman language is more inclined to take stock of itself, to weigh, and to offer something worth weighing.
