Erasmus takes us on a tour of the body and mind, pointing out each of the features that obviously suit us better to a life of mutual assistance and kindness, rather than one of fighting. A bull has horns and a crocodile has armor, but we have soft skin, embracing arms, and “friendly eyes, revealing the soul.” We laugh and cry, revealing our sensitivity. We have speech and reason, with which to communicate. We even have a natural attraction to the love of learning, which “has the greatest power of knitting up friendships.”
