How old is the term 哲学 as a name for philosophy?
The wikipedia page you quote literally says &quot;1874年，日本启蒙家西周，在《百一新论》中首先用汉语词“哲学”来翻译philosophy一词&quot;. So &quot;哲学&quot; as a word is as old as that.
The Classical Chinese occurrences are about the word &quot;哲&quot;, not &quot;哲学&quot;. They are not exactly the same thing.
