Daniel Dennett's Tools for Critical Thinking

Key Ideas & Facts:

1. Embracing Mistakes: Dennett encourages viewing mistakes as valuable learning opportunities. He advocates for rigorous self-examination of errors to avoid repeating them. "When you make a mistake, you should learn to take a deep breath, grit your teeth and then examine your own recollections of the mistake as ruthlessly and as dispassionately as you can manage." (Valeria Maltoni). This aligns with the scientific method, where errors are essential for progress.
2. Respecting Opponents: Dennett emphasises the importance of understanding and fairly representing opposing viewpoints before critiquing them. This fosters respectful dialogue and encourages a more receptive audience for one's own arguments. "Your targets will be a receptive audience for your criticism: you have already shown that you understand their positions as well as they do, and have demonstrated good judgment." (Valeria Maltoni & Open Culture).
3. The "Surely" Klaxon: Dennett warns against using the word "surely" as a crutch to avoid providing adequate evidence or reasoning. He suggests that its presence often signals a weak point in an argument, highlighting an assumption the author hopes the reader will blindly accept. (Valeria Maltoni & Open Culture).
4. Answering Rhetorical Questions: Dennett advocates for directly addressing rhetorical questions rather than dismissing them. He argues that answering these questions forces deeper examination of the underlying assumptions, preventing intellectual laziness. (Valeria Maltoni & Open Culture).
5. Employing Occam's Razor: This principle advocates for choosing the simplest explanation that adequately accounts for a phenomenon. "The idea is straightforward: don’t concoct a complicated, extravagant theory if you’ve got a simpler one (containing fewer ingredients, fewer entities) that handles the phenomenon just as well." (Valeria Maltoni & Open Culture). This helps avoid unnecessary complexity and unsubstantiated assumptions.
6. Avoiding Rubbish: Dennett cites "Sturgeon's Law", stating that 90% of everything is "crap". He encourages focusing on the 10% of high-quality arguments and avoiding wasting time on poorly constructed or biased claims, even if they align with one's ideology. (Open Culture & Farnam Street).
7. Beware of Deepities: Dennett cautions against "deepities", statements that sound profound but are actually ambiguous and ultimately meaningless. They appear important and true but rely on ambiguity to achieve this effect. He emphasizes the need for clear and precise language to avoid being misled by these deceptive statements. (Open Culture & Farnam Street).

Additional Tools:

• Mistake Connoisseur: (Farnam Street) Dennett advocates for actively reflecting on one's mistakes to learn from them. He suggests becoming a "connoisseur" of your own errors, examining them thoroughly to extract valuable insights.
• Composing Critical Commentary: (Farnam Street & The Marginalian) Dennett outlines a four-step process for constructing effective critiques. This process involves:

1. Clearly and fairly representing the opponent's position.
2. Identifying areas of agreement.
3. Acknowledging anything learned from the opponent.
4. Only then offering rebuttal or criticism.

• Occam's Broom: (Farnam Street) Dennett highlights the danger of using Occam's Razor to unfairly dismiss inconvenient facts that contradict one's preferred theory. He warns against this form of intellectual dishonesty.
• Jootsing: (Farnam Street) Dennett advocates for "jumping out of the system" to promote creative thinking. This involves challenging existing rules and assumptions within a given field to generate truly innovative ideas.
• Rathering: (Farnam Street) Dennett cautions against the misuse of "rathering", which creates false dichotomies by implying an incompatibility between two claims without proper justification.
