Bry Willis posits a radical perspective on truth, arguing it is primarily a rhetorical construct rather than an objective reality. They contend that disciplines like psychology and neuroscience, though presented as factual, are built upon a foundation of language and narrative, functioning more as persuasive systems than mirrors of truth. This perspective, labelled the Language Insufficiency Hypothesis, suggests language itself is inherently flawed for capturing reality, instead serving as a filter or veil. Ultimately, the text proposes that what we perceive as truth is simply dominant or widely accepted narratives, maintained by their persuasive power and institutional backing.
