Why is "to attempt" written as 心 + 見る？


Why is こころ + みる the word used to say "to try/attempt"? What is it supposed to
be saying as an idiom?




When I did a sentence search on jisho.org for こころみる, there were several
sentences for the 試みる version and none for the 心見る version, suggesting that it
is likely antiquated to the point of being irrelevant in modern Japanese. In
other words, if it's not a usage that you're likely to see or to use, does it
matter where it came from? But I guess if you're just wondering for the sake
of curiosity, perhaps a native speaker with a deep knowledge of outdated kanji
could explain.
