That man lives happy and in command of himself, who from day to day can say I have lived. Whether clouds obscure, or the sun illumines the following day, that which is past is beyond recall.
It will be practicable to blot written words which you do not publish; but the spoken word it is not possible to recall.
[Lat., Delere licebit
Quod non edideris; nescit vox missa reverti.]
