In everyday life it is most necessary to have control over speech and action, for one may automatically give way to a word, prompted by an inner impulse; afterwards one finds that one should not have said it, or perhaps one should have said it differently. It is the same with action. One feels, "I should not have done so", after having done something; or one thinks, "I should have done differently"; but once it is done it is too late to do it otherwise. In human nature there is an inner urge to express oneself; and that urge pushes a word out of one, so to speak, before one has really thought of it; and all this shows lack of control over oneself.
