“What! all of us, Christians, not only profess to love one another, but do actually live one common life; we whose social existence beats with one common pulse—we aid one another, learn from one another, draw ever closer to one another to our mutual happiness, and find in this closeness the whole meaning of life!—and to-morrow some crazy ruler will say some stupidity, and another will answer in the same spirit, and then I must go expose myself to being murdered, and murder men—who have done me no harm—and more than that, whom I love. And this is not a remote contingency, but the very thing we are all preparing for, which is not only probable, but an inevitable certainty.”

Context: Were we all like the Sawhorse, we would all be Sawhorses, which would be too many of the kind. Were we all like Hank, we would be a herd of mules; if like Toto, we would be a pack of dogs; should we all become the shape of the Woozy, he would no longer be remarkable for his unusual appearance. Finally, were you all like me, I would consider you so common that I would not care to associate with you. To be individual, my friends, to be different from others, is the only way to become distinguished from the common herd. Let us be glad, therefore, that we differ from one another in form and in disposition. Variety is the spice of life, and we are various enough to enjoy one another's society; so let us be content.
