Context: My marriage brought great happiness into my life, but lately there's been nothing but sadness. I understand that love and tragedy go hand in hand, for there can't be one without the other, but nonetheless I find myself wondering whether the tradeoff is fair.

On the other hand, the law holds with equal sureness for all right action. Love, and you shall be loved. All love is mathematically just, as much as the two sides of an algebraic equation. The good man has absolute good, which like fire turns every thing to its own nature, so that you cannot do him any harm; but as the royal armies sent against Napoleon, when he approached, cast down their colors and from enemies became friends, so disasters of all kinds, as sickness, offence, poverty, prove benefactors:
