21. Sometimes even when haste is most incumbent on us, the delays that slow our progress may bring such honour, that often we shall be glad to have been thwarted of our purpose. For instance, take the case of persons who are compelled to journey in such high haste, that they prefer the perils of the saddle to a seat in a carriage on account of the trouble caused by their baggage, the weight of the vehicle, the delays to progress, the roughness of the track, not to mention the boulders that beset the route, the tree trunks fallen across the way, the rivers that intersect the level, and the steep slopes of the mountains. Well, then, those who wish to avoid all these obstacles select a horse of tried endurance, mettle, and speed, that is to say, one strong to bear and swift to go, like the horse described by Lucilius that _With one sole stride o'erpasses plain and hill._ None the less, if as this horse bears them along on the wings of his speed, they chance to see some great personage, a man of noble birth, high wisdom, and universal fame, then, however pressing their haste, they refrain their speed that they may do him honour, slacken their pace and rein in their horse: then straightway leaping to the ground they transfer to their left hand the switch, which they carry wherewith to beat the horse, and with right hand thus left free approach the great man and salute him. If it please him for a while to ask questions of them, they will walk with him for a while and talk with him: in fact they will gladly suffer any amount of delay in the performance of the duty which they owe him. _On the Virtues of Crates._
