خِلَافًا لِلسُّوفَسْطَائِيَّةِ
In opposition to the sophistical positions.
The term “sophists” here serves as an umbrella for several strongly skeptical theses concerning reality and knowledge. Those theses are not identical.
One denies determinate realities, another treats their status as dependent on belief, and a third questions knowledge of both existence and nonexistence.
These are categories used in the theological discussion, not a warrant to assign one uniform doctrine to every historical philosopher or everyone who asks skeptical questions.
