"Clearly" refers to the obviousness or self-evidence of the statement. In this context, "just" means "similarly" or "in the same way," or ig "exactly" if you like.

"Clearly" because exterior stimuli clearly influence both thinking and feeling, a concept supported by common experience and scientific understanding of human cognition and emotions.

How are all of these measured?

[MeImCounting]

Theres actually a ton of different ways. The most obvious is probably MRIs of which many have been conducted with the subject having a huge variety of different stimulus. Then theres the good old fashioned behavioral studies ranging from the classic "does the subject jerk their hand back in the presence of heat?" to the more recent hungry judge phenomenon.

I wouldnt think the fairly self evident assertion that exterior stimulus changes both the internal state of a person as well as their behavior would be controversial.

At this point in history "free will" is really just the god of the gaps and those gaps shrink every year. Its probably a useful religious concept but as far as reality goes its the least interesting question one could ask about the whole human experience.

Influence != Determine

Yes it is indeed possible that in that small and shrinking gap of behavior that isnt explained by some complex set of circumstances and stimuli there lies some magic immaterial soul that grants the ineffable quality of free will. Bbbut since we have yet to find any evidence for such a thing I wouldnt keep my hopes up. Also theres much more interesting questions to be asking.
