Is this a reasonable pair of premises?: (I hope I have phrased them well.)
If what is thought is concieved as having extension, it’s place when known must have extension;
if a thought does not have extension, it’s place will have no extension.
The premises are part of an argument to show that man has a spiritual soul.
To be clear, “thoughts that have extension” basically refers to the imagination or “phantasm”.
Well, they aren’t completely different: the form in the mind is the form of the object thought of – which comes from objects to the mind through the senses. …At least that’s my understanding. (no pun intended)
