On The Estate of Cleonymus (12-13)

His subsequent conduct is the strongest proof in support of our contention, that even in acting thus he did not intend to injure us. For after Deinias's death, when things were going badly with us, he would not allow us to lack anything, but took us into his own house and brought us up, and saved our property when our creditors were scheming against it, and looked after our interests as though they were his own.

It is from these acts rather than from the will that his intentions must be discerned, and inferences must be drawn not from what he did under the influence of anger—through which we are all liable to err—but from his subsequent acts, whereby he made his attitude quite clear. In his last hours he showed still more plainly his feelings toward us.
