Seneca · On the approaches to philosophy

Letters 108.8

It is easy to rouse a listener so that he will crave righteousness; for Nature has laid the foundations and planted the seeds of virtue in us all. And we are all born to these general privileges; hence, when the stimulus is added, the good spirit is stirred as if it were freed from bonds. Have you not noticed how the theatre re-echoes whenever any words are spoken whose truth we appreciate generally and confirm unanimously?
