Effects of Language on Perception and Belief On my view...
All thought and belief, ranging from the simplest to the most complex, consists entirely of mental correlations drawn between different things. If intentional and deliberative thought is a kind of thought, and I'm right about what all thought and belief consists in/of, then intentional and deliberative thought consists of mental correlations satisfying whatever counts as being intentional and deliberative thought as compared/contrasted to/with other kinds.
Having been interested in doing philosophy for some time, I've a significant amount of uncertainty regarding the criterion another is working, especially in situations such as this one, as it is quite the nuanced conversation. Common sense tells me that that name could be rightfully, meaningfully, acceptably, and/or sensibly used in a plurality of differing ways, not all of which are amenable to one another. More plainly put, it could be used to pick out all different sorts of things, including many things that are not what I'm picking out to the exclusion of all else. Hence... my apprehension is prevalent.
Here's the simpest use/sense of that term that makes perfect sense to me...
Intentional and deliberate thought always consists of a creature focused upon something in particular. That kind of thought and belief would show itself early on. If such thought existed in it's entirety prior to language use, then it does not consist of language use.
Language use could become the focus. Language use certainly helps determine the focus. Language use can and does become an integral elemental constituent of the thought and belief of language users. Language use becomes a necessary elemental constituent of thought when that thought includes mental correlations being drawn between language use and something else.
Intentional and deliberate thought does not always include language, but certainly can.
So, how does language use effect/affect intentional and deliberate thought?
It broadens the scope.
