Reason and rationality are way to see the world. Logic is an intellectual tool.

One can use logic to an irrational view of the world

That’s not quite right either.

Rationalize

attempt to explain or justify (one’s own or another’s behavior or attitude) with logical, plausible reasons, even if these are not true or appropriate.

Oxford Dictionaries

All reason and rationale must be logical based on available evidence and knowledge.  The fact that all observations are relative, allows for several complimentary perspectives. When any of these fundamentals are in conflict something is wrong with the perception or understanding of the data.
