Podcast Summary: The Strange Search for Knowledge in the Age of Post-Truth

Podcast: Philosophy For Our Times
Host: IAI (Interviewer: Ed)
Guest: Steve Fuller, Professor of Sociology, University of Warwick
Date: March 3, 2026

Overview

This episode explores the changing landscape of knowledge in what has come to be called the “age of post-truth.” Steve Fuller, noted for his pioneering work in social epistemology, challenges traditional notions that knowledge is created by experts within established institutions, advancing toward a single, universal truth. Instead, Fuller argues that knowledge is socially contingent—shaped by diverse communities and affected by mediums like social media and technologies such as AI. Fuller considers whether the post-truth condition is actually a recognition of this social complexity and what the emancipatory role of education should be in this context.

Key Discussion Points & Insights

1. What is Social Epistemology? (01:23–04:58)

• Social epistemology is the study of the social foundations of knowledge: both how knowledge is produced and how it ought to be produced.
• It is fundamentally interdisciplinary, drawing from philosophy, history, economics, social sciences, and humanities.
• Quote:

  "None of the specific disciplines, whether we're talking about philosophy or the humanities or the social sciences, actually deals directly with this matter. And Social Epistemology is meant to sort of put them all together..."
  — Steve Fuller (01:54)

2. Defining Knowledge: Social and Methodological Dimensions (03:00–04:58)

• Recognition by a community is crucial; knowledge is not just individual belief.
• Knowledge is not merely consensus or popularity, but involves public testing, argumentation, and rational agreement—reflected in the scientific method.
• The scientific method is seen as the current “gold standard,” but still a social process open to discontinuity and contestation.

3. The Historical Development of Knowledge (05:04–09:27)

• In the ancient world (Greeks, Plato, Aristotle), knowledge was pursued as a single-lifetime achievement, akin to Eastern traditions.
• The 17th-century shift—exemplified by the Royal Society—introduces the concept of knowledge as an intergenerational, cumulative process.
• This introduces "historicity"—a modern view that knowledge builds over multiple lifetimes.
• Quote:

  "The whole point of science in the modern era is something different because in a sense, it kind of...forces you to think that you might not actually get knowledge in your lifetime..."
  — Steve Fuller (07:22)

4. Post-Truth: Crisis or Correction? (09:27–13:13)

• Recent decades have seen fragmentation of the narrative of progress and challenges to the idea of a single truth.
• The 20th century, marked by both unprecedented advancements and devastating consequences (wars, environmental crisis), led to doubts about whether knowledge inevitably leads to good.
• "Post-truth" arises not from the end of knowledge, but skepticism towards a single, universal direction for knowledge.
• Quote:

  "All of this doubt reflecting on, let's say, the last hundred years that are leading people to wonder, well, are we going in the right direction?"
  — Steve Fuller (11:44)

5. The Post-Truth Condition: Positive Potential? (13:13–15:13)

• Post-truth accommodates multiple perspectives and standards for validation.
• Social media, rather than undermining knowledge, democratizes the process and makes audiences sharper and more critical.
• Institutions are unsettled because validation is taken into users’ own hands—a logical consequence of mass education.
• Quote:

  "People are taking the validation process into their own hands... We are living in a world where we have the most educated people ever."
  — Steve Fuller (14:00)

6. The Role of Education (15:13–17:33)

• Fuller strongly advocates for education as an emancipatory force suited for the post-truth context.
• Suggests early education in digital literacy and basic programming so that people understand how information is constructed.
• The means of media production are now accessible to ordinary people, not just authorities.
• Quote:

  "What kids need to learn is how that works exactly, not just at the level of, of the user friendly apps that they have in their smartphones that enable them to access stuff, but also what goes into the programming. And that could be introduced as a part of basic literacy."
  — Steve Fuller (16:07)

7. Power, Technology, and Social Media (17:33–18:39)

• The control of social media by tech billionaires is a problem of capital concentration rather than competence.
• Skill and knowledge ("competence") are widespread; it’s political economy that determines who controls platforms.

8. Technology, Knowledge, and Media (19:22–21:45)

• The medium through which knowledge is communicated profoundly shapes how it is adjudicated.
• Writing gave rise to authoritative texts and allowed for rigorous claims about truth and validity.
• Social media radically democratizes this process—the authority attached to written forms is now decentralized.
• Quote:

  "When you get to written culture...you have to get the notes right...And I think that's where the truth issue comes in. It comes in actually with that medium, with the written medium."
  — Steve Fuller (20:20)

9. AI, ChatGPT, and the Democratization of Knowledge (21:45–26:16)

• AI like ChatGPT "undoes the mystique of creativity" and accesses a far wider range of texts than humans typically do—potentially "redeeming" forgotten or ignored knowledge.
• AI reads with fewer prejudices than academia, which tends to ignore 80% of published work.
• In epistemology, the concern isn’t the distinctions themselves, but the kind of distinctions—AI may help uncover overlooked connections and value.

10. The Power of the Medium (26:16–28:37)

• Social media and AI are not just content-neutral carriers; they reshape how knowledge is produced, recognized, and disseminated.
• Academics and institutions should focus more on the medium—moving beyond text-centric modes to explore other, possibly more effective, forms of expression.
• Quote:

  "Content isn't really the problem. The problem is the medium and what the medium allows you to say and not say."
  — Steve Fuller (26:50)

11. Case-by-Case Knowledge Mediation (28:37–28:49)

• Fuller emphasizes a case-by-case approach in identifying the best medium for particular kinds of knowledge dissemination.

Notable Quotes

• "Social epistemology is basically at the most basic level, the social foundations of knowledge." — Steve Fuller (01:40)
• "It’s not just automatic consensus, it's not just a popularity contest what knowledge is. So the question then becomes, what is the form of organization by which you combine opinions and test opinions?" — Steve Fuller (03:28)
• "The knowledge you want is the knowledge for your lifetime...The next generation will have to figure this out for themselves." — Steve Fuller (08:48)
• "Post-truth...is not like we all are heading in the same direction anymore...It's the recognition of difference and then somehow managing it." — Steve Fuller (12:12)
• "The sheer phenomena of the disagreement is not itself a problem." — Steve Fuller (15:07)
• "Social media democratizes the process of production." — Steve Fuller (16:35)
• "It's not a competence problem. It's not like the guys in Google and Microsoft know more than the hackers. No, it's just they have more power." — Steve Fuller (18:00)
• "ChatGPT does not have those biases...it can access that stuff and then come up with more novel combinations and more novel forms of knowledge." — Steve Fuller (23:30)
• "Content isn’t really the problem. The problem is the medium and what the medium allows you to say and not say." — Steve Fuller (26:50)

Memorable Moments

• Fuller compares the democratization of publishing via social media with the earlier historic shift from orality to print, suggesting social media is reshaping truth standards.
• The point that 80% of academic work is unread except by AI, and that this may open new doors for knowledge when mined by generative models.

Tone

The conversation remains accessible and conversational but maintains philosophical rigor. Fuller frequently references historical context for philosophical ideas, using analogy and plain language to demystify complex concepts. The interview maintains an optimistic but realistic outlook about technological change and the nature of knowledge.
