Rather i think Torquatus is making the more striking idea that all mental pleasures and pains are based on the five senses specifically in either recollection, present experience, or anticipation of sensations of sight, sound, touch, etc. Which i sought to defend.
Oh, I'm agreeing with your premise! My only amplification is that we need a body to even be able to experience the world through the senses. There are no sensations without the ear, eye, tongue, skin, nose, and mind/soul/psykhē working in concert.
