I came across this sentence:
Marriage is -- first and foremost -- a societal institution, which is why it is only natural that it would primarily be formed in a magistrate.
I find this argument to be overly-simplistic, because it appears to ignore all the cultural background of marriage as an institution. But if I had to describe this argument, I would like to use an adjective that draws attention to its "rationality". I'm not really sure how to describe it. To me the argument seems too focused on being rational (i.e. based on cold hard logic), and in doing so it ignores the more humane aspects of marriage, which in my opinion is un-wise.
That's how I feel, and that's what I'd like to communicate.
Is there any (probably uncommon and advanced-level) adjective that would help me communicate my thoughts? A bit longer expressions are also fine, it doesn't need to be one single word. I'm just looking to expand my vocabulary.
