I agree. I wonder what it means to say we are "rational"? It seems "intuitive" would fit us better.
Even when I am reading something scientific or mathematical and I finally, after reading it many times, say to myself, "Oh, yeah, that's reasonable." Or, "Oh, yeah, that makes sense." I don't mean that I went through some rational process or that I had a sense experience of the theorem. I just finally understood it intuitively.
