“The soul never thinks without an image”. Really?

unfortunately this quote

“The soul never thinks without an image.”
– Aristotle

Is incomplete and outdated, because it suggests that blind people since birth would not have soul or would not think.

I’ve read a masters thesis that explains that intelligence is not defined by input / output sensory systems but by processing information and coming with conclusions… as thinking is not limited by visual means, that blind people since birth are intelligent and visual input is only one of many; hence the soul thinks with many means
inclusive various without images. ( visual input)

But this also makes me think, what is image?

Is the definition of image limited only to the visual input? Really?

Is the soul same as intelligence?

I need your views please!
