Reflecting in such random fashion, and strolling with no greater method, I worked my way back through Cheapside and found myself once more in front of Sweeting's window. Again the turtles attracted me. They were alive, and so far at any rate they agreed with me. Nay, they had eyes, mouths, legs, if not arms, and feet, so there was much in which we were both of a mind, but surely they must be mistaken in arming themselves so very heavily. Any creature on getting what the turtle aimed at would overreach itself and be landed not in safety but annihilation. It should have no communion with the outside world at all, for death could creep in wherever the creature could creep out; and it must creep out somewhere if it was to hook on to outside things. What death can be more absolute than such absolute isolation? Perfect death, indeed, if it were attainable (which it is not), is as near perfect security as we can reach, but it is not the kind of security aimed at by any animal that is at the pains of defending itself. For such want to have things both ways, desiring the livingness of life without its perils, and the safety of death without its deadness, and some of us do actually get this for a considerable time, but we do not get it by plating ourselves with armour as the turtle does. We tried this in the Middle Ages, and no longer mock ourselves with the weight of armour that our forefathers carried in battle. Indeed the more deadly the weapons of attack become the more we go into the fight slug-wise. Slugs have ridden their contempt for defensive armour as much to death as the turtles their pursuit of it. They have hardly more than skin enough to hold themselves together; they court death every time they cross the road. Yet death comes not to them more than to the turtle, whose defences are so great that there is little left inside to be defended. Moreover, the slugs fare best in the long run, for turtles are dying out, while slugs are not, and there must be millions of slugs all the world over for every single turtle. Of the two vanities, therefore, that of the slug seems most substantial.
