I suppose we may be using "observation" in different ways. — Metaphysician Undercover
Perhaps. For me, everything in its place: sound sensation is hearing, tactile sensation is feeling, olfactory sensation is smelling.....sight sensation is seeing, and that which is seen is observed. We do not observe the smell of frying bacon, we do not taste B-flat, and we do not hear the sight of fast-moving clouds.
To me, observation implies judgement having been past on the acts of sensation, such that a decision as to what will be remembered out of all that has been sensed, has been made — Metaphysician Undercover
From the above, it is clear any sensation has its possible judgement, but their respective sources, hence the conceptions under which they are subsumed, will be completely different. Observation directly requires extension of matter in space, for instance, but the sensation of sound only directly requires changes in air pressure, which is not required by extension.
Judgement passed on sensation, rather than being mere observation, is empirical knowledge. Sensation upon which a judgement is not forthcoming, insofar as we must admit to an “I don’t know” about it, still manifests as an experience. Aesthetic judgements, on the other hand, those having to do with non-cognitive feelings, or the sublime, are just the opposite, insofar as, while possibly motivated by experience, are not themselves judgements of experience, thus knowledge with respect to them is given immediately.
Obviously, empirical judgements are susceptible to change with sufficient subsequent experience, but aesthetic judgements are not so susceptible, being grounded in the subject’s innate sense of quality, re: Hume’s “missing shade of blue”
gedankenexperiment.

Reason, being conditioned only by itself, would have the capacity to produce any sort of fantasy, any imaginary thing. — Metaphysician Undercover
Yep. Self-control is not intrinsic to reason. We can certainly imagine anything we like, except the logically impossible. Which is ironic, because only reason gives the laws of logic, which reason then uses to control itself. So perhaps we trust reason over sensation because reason belongs to us, is present constantly, and if we didn’t trust it, we couldn’t claim to know anything whatsoever, including the very same laws of logic, the principles of mathematics, and even our own selves, which is absurd.
Nevertheless, if one chooses to trust sensation over reason, he will be at a complete loss as to explaining what the sensation actually represents, unless he reasons about it, which puts him right back to trusting reason over sensation.
