In any event...

In any event, without going into a historical investigation concerning the existence of such people and inquiring into the motivation behind such views or the verity of their ascription to those who are claimed to have held them, we take them as doubts or questions that require an answer suitable to philosophical discussion, leaving the subject of historical fact to be decided by historical research.

A Survey of the Claims of the Skeptics That which has been reported of the statements of the sophists and the skeptics may be divided from one angle into two parts: one having to do with what they have said about existence and being, and the other concerning what they have expressed about science and knowledge. That ْis, their statements have two aspects: one aspect concerns the subject of ontology, while the other pertains to epistemology.

For example, the remark is attributed to one of the most extreme of the sophists, Gorgias : “Nothing exists, and if there were anything, it could not be known, and even there were knowledge of being, this knowledge could not be communicated to others.”
