 We cannot possibly agree with the Stoics that pain is not bad. Perhaps pain is not always bad in its effects—it can offer useful warnings, sometimes even strengthens physical organs just as it impresses greater energy and strength of will to morality. […] But if pain was not an evil it would not be so for others anymore than for ourselves. We should discount it in others and in ourselves. So why this tender humaneness that characterizes the greatest stoics much more than the firmness and the constancy of their virtues? (Cabanis 1824: 84)
