Logic and Sense Knowledge

I think that logic can be viewed as a type of gradualism that is water tight and invaluable in moving us toward a genuine source of knowledge or truth. However it does appear that there are other mechanisms which use a more punctuated approach, that while not as stringent in its application, and indeed not as gradual, use value judgement acting on sensory information to reach a similar conclusion. Is the latter a type of reason? I too would argue yes. Can it be reduced? Possibly. But perhaps something is lost in doing so. Maybe it functions on a level that bypasses the need for mini-steps, chunking information in bigger bytes to reach its endpoint with a greater efficiency.
