Cicero writes in his disputations
…..it must follow, then, that death cannot be an evil; or that it must rather be something desirable; for if either the heart, or the blood, or the brain, is the soul, then certainly the soul, being corporeal, must perish with the rest of the body; ….
He then asks
What shall I say of Dicearchus, who denies that there is any soul? In all these opinions, there is nothing to affect any one after death, for all feeling is lost with life, and where there is no sensation, nothing can interfere to affect us.
I don’t know about you, but as for me, having no coherent idea of what the soul is and having had no prior idea of life on earth before I was born, the future life doesn’t interfere with how I live today.
