When we are as yet small children, long before the time when those two grown ladies offer us the choice of Hercules, there comes up to us a youthful angel, holding in his right hand cubes like dice, and in his left spheres like marbles. The cubes are of stainless ivory, and on each is written in letters of gold—Truth. The spheres are veined and streaked and spotted beneath, with a dark crimson flush above where the light falls on them and in a certain aspect you can make out upon every one of them the three letters, L, I, E.
The child to whom they are offered very probably clutches at both. The spheres are the most convenient things in the world; they roll with the least possible impulse just where the child would have them. The cubes will not roll at all; they have a great talent for standing still, and always keep right side up.
