Pronunciation: [sˈə͡ʊ fˌɑːɹ az wˈɒn kan sˈiː] (IPA)
When it comes to describing the limits of one's knowledge or understanding, the phrase "so far as one can see" is a common choice. However, there are several other alternatives that can be used to convey a similar meaning. One such synonym is "as far as one knows," which suggests that the speaker's understanding may be limited, but they are confident in what they do know. "To the best of one's knowledge" is another option that conveys a sense of uncertainty along with a commitment to accuracy. Other synonyms include "as far as can be determined," "to the extent of one's awareness," and "to the best of one's abilities".
