epistemology: room for thought

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.

no thought has extention

the things about which one thinks may have extention but the things thought and the things themselves are completely different things…

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)

no, no thought has extension…

a thought is “in your head” and that’s it.

yes, they are completely different…

one is “in your head” the other apparently exists outside of you…
