Disinterestedness is a necessary attribute to real friendship and it is the duty of one friend to guess another's problems and render assistance before it is asked. If our friends have needs that we can satisfy, we should relieve them of the necessity of seeking our help. Apart from the satisfaction usually produced by an action, this permanent ability to give pleasure is perhaps the only advantage of wealth and power.
