Seneca · On the vitality of the soul and its attributes

Letters 113.25

The dispute is settled, and we are therefore agreed. For I shall admit, meanwhile, that the soul is a living thing with the proviso that later on I may cast my final vote; but I deny that the acts of the soul are living beings. Otherwise, all words and all verses would be alive; for if prudent speech is a Good, and every Good a living thing, then speech is a living thing. A prudent line of poetry is a Good; everything alive is a Good; therefore, the line of poetry is a living thing. And so “Arms and the man I sing,” is a living thing; but they cannot call it rounded, because it has six feet!
