What he failed to understand, and you do as well, is that there is a great deal of subjectivity in coming to ultimate conclusions
One’s scientist’s subjectivity is another’s illogic. Maybe one day logic will have room for subjectivity, but as any Star Trek fan will tell you, that day is still well in the future on Vulcan. As well as in the faculty lounges of the physics departments of MIT, Harvard, Stanford, Caltech, Princeton, Chicago, etc.
No conclusion that admits subjectivity deserves the epithet “ultimate.”
