To distinguish this from the "establish" meaning of "found": if the sentence still makes sense when you replace "found" with "discovered", it is the past tense of "find". This is by far the most frequent use of the word "found" in everyday English.

文法句型

be founded on/upon + noun phrase (basis)

found + abstract noun + on/upon + noun phrase

用法筆記

Almost always followed by 'on' or 'upon'. The object of the verb is typically abstract — a belief, claim, theory, opinion, argument, or relationship. The passive form is more common than the active. In everyday English, 'based on' is used instead; 'founded on' is more formal and feels more emphatic.
