In this deep dive into epistemology, the host of ToKCast argues that the concept of 'belief' is a misleading and potentially dangerous relic of pre-Enlightenment thinking, advocating instead for a Popperian and David Deutsch-inspired framework where knowledge is understood as 'information with causal power.' Drawing on analogies from physics (Einstein’s relativity replacing Newtonian force) and biology (natural selection over Lamarckism), the host contends that belief—especially in its religious or dogmatic forms—introduces epistemological confusion by conflating subjective certainty with objective truth. The episode dismantles the idea that strong feelings or 'degrees of belief' are relevant to rationality, emphasizing instead that behavior is driven by knowledge, not belief. Even false knowledge—like Newton’s law of gravity—can be useful and cause real-world effects, making it valuable despite its falsity. The host critiques the notion that belief is necessary to explain human action, asserting that knowledge, not emotional attachment, is the true driver of behavior. He concludes by calling for a complete rejection of belief in favor of critical, fallible, and evolving knowledge, positioning this shift as essential to progress, rationality, and the ongoing project of the Enlightenment.
Knowledge is information with causal power, not belief; it's what drives behavior, not emotional conviction.
Belief is a subjective psychological state that distracts from objective epistemology and can enable dogma and violence.
Even false knowledge (like Newton’s gravity) can be useful and cause real-world effects, so we should use it without needing to 'believe' it.
Rationality is the capacity to detect and correct errors—not just having the ability, but actively applying criticism.
The deeper problem than dogma is the absence of error correction; without it, belief becomes entrenched and dangerous.

The Problem with Belief in Epistemology
“Belief might be a distraction. Anyway, so the purpose of this is to respond to a comment underneath the YouTube video of one of the encounters that I had with the great Peter Bukosian.”
The Contradictory Nature of 'I Believe'
“In the first case, it's completely superfluous... In the second case, it's superfluous because you could just say I don't know exactly but I guess he's from Utah.”
Knowledge as Information with Causal Power
“Knowledge is information with causal power. It's the information that actually does stuff.”
Belief vs. Knowledge in Human Behavior
The host argues that people act on knowledge, not belief. Even strong emotional attachment to an idea is irrelevant; what matters is whether the idea has causal power and can be criticized.
The Enlightenment as a Tradition of Error Correction
The host frames the Enlightenment not as a set of beliefs, but as a tradition of criticism and error correction—the true engine of progress, which undermines dogma and belief-based systems.
“We should embrace this deeper explanation of why people do what they do in terms of the knowledge instantiated in their brains rather than the emotional attachment that some people claim to have about their beliefs.”
“Knowledge is information with causal power. It's the information that actually does stuff.”
“Dogma is the fundamental moral crime which grounds all other moral crimes.”
