he grew old learning many a fresh lesson every day. - Cicero

How long will men dare to call anything expedient that is not right? Can odium and infamy be of service to any empire, which ought to be supported by glory and by the good-will of its allies? I was often at variance even with my friend Cato. He seemed to me to guard the treasury and the revenues too obstinately, to refuse everything to the farmers of the revenue, and many things to our allies; while we ought to be generous to our allies, and to deal with the farmers of the revenue as leniently as we individually do with our own tenants, especially as the union of orders to which such a course would conduce is for the well-being of the state.

We don't practise generosity in order to secure gratitude, nor do we invest our gifts in the hope of a favourable return. Rather, it is nature that inclines us towards generosity. Just so, we don't seek friendship with an expectation of gain, but regard the feeling of love as its own reward.
