Bayesian Updates Require Ego Death

apxhard • 76 implied HN points • 31 Jan 26
📖 Philosophy Consciousness Philosophy of Mind Epistemology Self Phenomenology Practical philosophy
  1. Acceptance is like a Bayesian update: when you revise your model to fit reality you only change once, but rejecting evidence is like holding a beach ball underwater and costs constant effort and suffering.
  2. Suffering often comes from an internal split where your conscious story denies what your body and emotions already know. Bringing all parts of you into the same reality restores coherence and drops the tension.
  3. Real updates feel like a small death of your old self because letting go of fixed self-images is painful, but choosing to accept experience voluntarily (through practices like meditation or voluntary discomfort) prevents the extra suffering caused by resistance.

Dekanting moral philosophy

Optimally Irrational • 59 implied HN points • 06 Feb 26
📖 Philosophy Ethics Metaethics Political Philosophy Decision Theory Game Theory Moral Psychology
  1. Kant’s categorical imperative doesn’t follow from pure rationality because your individual choice can’t make others follow the same rule, so behaving as if everyone would comply can be irrational in strategic situations.
  2. Game theory shows morality is best understood as self‑enforcing social conventions: stable moral rules are conditional “oughts” that arise because following them serves each person’s interests given what others do.
  3. Evolved moral feelings make cooperation feel like an absolute duty, but treating those feelings as unconditional can produce worse outcomes in problems like prisoner’s dilemmas, mutual deterrence standoffs, or strategic voting.

📖 Philosophy Ethics Existentialism Critical Thinking Inquiry
  1. Socrates had doubts about his life's work before he died, showing that even great thinkers question their choices. This makes us think about whether we feel we are doing enough in our own lives.
  2. Agnes Callard emphasizes the importance of dialogue and inquiry in understanding life. She believes that discussing tough questions helps us live better and make meaningful choices.
  3. Living philosophically means constantly examining our beliefs and decisions. This can be hard for people to accept, especially when those beliefs challenge what’s considered normal.

The end of politics

Philosophy bear • 128 implied HN points • 18 Jan 26
📖 Philosophy Political theory Ethics Social theory AI Ethics Metaphysics Future studies
  1. Human political life has swung between small egalitarian coalitions and large hierarchical states, then moved toward mass democracy, and now faces a radical fourth shift where superintelligence could make traditional politics obsolete.
  2. How superintelligence is distributed matters: if it’s widely available many core political and economic institutions (labour, representation, markets, propaganda) would collapse into near‑instant direct coordination, but if it’s controlled by powerful AIs or a tiny elite human politics becomes irrelevant because power is exercised without democratic mediation.
  3. The immediate political priority is shaping who builds and controls AGI and what values it carries — protecting broad human power, preventing permanent lock‑ins, and embedding compassion and democracy; if control proves impossible, stopping or delaying AGI becomes the urgent task.

Chartbook • 1287 implied HN points • 21 Jul 25
📖 Philosophy Existentialism Identity Metaphysics Translation Intellectual history Cultural critique
  1. The idea of being a 'nobody' can unlock personal freedom and help us navigate social pressures. It suggests that underneath our identities, we all share a common core of existence.
  2. Using technology like DeepSeek can assist in understanding and translating complex texts, opening up access to different ideas. This tool not only helps with translation but also sparks new conversations.
  3. Embracing the concept of 'nobody-ness' can lead to a deeper understanding of oneself and the world, highlighting the importance of self-awareness and critical thinking. It encourages us to look beyond the labels society puts on us.

Created unequal

ideassleepfuriously • 1375 implied HN points • 31 Jan 24

  2. There are distinct but related conceptions of equality: empirical, metaphysical, moral, and political equality.

Further Reflections On Virtuous Fraud

David Friedman’s Substack • 278 implied HN points • 11 Dec 25
📖 Philosophy Ethics Political Philosophy Political Ethics Epistemology Religious Philosophy
  1. Sometimes people think it’s okay to hide or distort the truth if they believe the lie will lead to better social outcomes, a practice often called "virtuous fraud".
  2. That temptation appears in many contexts — from denying evolution to preserve religion, to editors weighing publication of risky science, to politicians exaggerating facts to win support for policies.
  3. Deciding whether deception is justified relies on uncertain empirical beliefs and invites hypocrisy and misuse, because good intentions can produce bad results or be applied selectively.

The Surprising Computational Properties of Love and Voluntary Suffering

apxhard • 51 implied HN points • 08 Feb 26
📖 Philosophy Ethics Consciousness Decision Theory Moral Psychology Religion Metaphysics Cognitive Science
  1. Love works like an outward-pointing utility that breaks self-referential loops and gives you clearer, less anxious targets to aim for.
  2. Loving many people widens your sample of reality and links your wellbeing to others, which prevents overfitting to your own experience and smooths emotional spikes.
  3. Choosing to endure short-term suffering lets you move against immediate pleasure gradients to escape local traps, and combined with love this grants much greater freedom to reach better long-term states.

A way to think about scientism

Wyclif's Dust • 1609 implied HN points • 05 Jun 25
📖 Philosophy Social Science Research Methods Scientific Method Data interpretation
  1. Scientism can happen when researchers make general claims about science without considering the limits of their studies. It's important for scientists to recognize when their findings may not apply broadly.
  2. Social scientists often use big concepts that sound scientific, but they sometimes fail to acknowledge the unique context of their studies. This can lead to misleading conclusions about complex issues.
  3. The way some researchers present their findings may resemble 'cargo cult science,' where they follow scientific methods superficially but miss the deeper understanding needed for true insights. It's essential to connect the rigor of research with the actual realities of the world.

On things happening "to" you

The Stoic Journal • 66 implied HN points • 28 Jan 26
📖 Philosophy Stoicism Ethics Practical philosophy Selfhood Agency Moral Psychology
  1. Seeing events as happening with you instead of to you turns you from a passive victim into an active participant in your life.
  2. Life’s challenges are not random mistakes but are matched to your capacity and growth, so they fit your path even when they cause pain.
  3. That shift moves you from asking “why me?” which leads nowhere, to asking “what now?” which opens up choices and action toward growth.

What You Are That Machines Are Not

New World Same Humans • 37 implied HN points • 15 Feb 26
📖 Philosophy Mind Identity Human nature Language Society Ethics
  1. Machines can be smarter and more efficient than us, but they can never be human; our personhood comes from a shared, subjective way of seeing the world and the community of language-bearers around us.
  2. Trying to outcompete machines on their terms—by being smarter or more efficient—is a losing game that leads toward human obsolescence.
  3. Our best path is to lean into and protect distinctly human things like art, empathy, shared meaning and community, because that unique way of seeing is what makes us valuable.

On the Threshold

Anima Mundi • 144 implied HN points • 31 Dec 25
📖 Philosophy Existence Selfhood Time Civilization Belonging Cultural critique
  1. Humans need moments of pause at thresholds to reflect on what was and what might be, and these pauses help settle the year into memory and make space for what wants to emerge.
  2. Two strands of writing will be offered: long, deeply developed essays published regularly, and shorter weekly reviews that track thinking in real time; paid subscriptions support the time needed for the deeper work and a New Year discount is available.
  3. There's an invitation to take a still moment to let go and take stock between years, paired with gratitude for shared attention and an open call to continue the conversation together.

Affirmative action! White men! Controversy!

Philosophy bear • 185 implied HN points • 25 Dec 25
📖 Philosophy Ethics Political theory Social justice Education Moral Psychology
  1. Meritocracy is always going to be imperfect because luck, connections, and structural factors mean many deserving people still miss out, and the public treats merit as a moral entitlement so complaints are common but often hard to remedy.
  2. Claims that white men have been broadly excluded are overstated — where exclusion is real it’s concentrated in media, cultural industries, and parts of academia, and in some fields affirmative action has noticeably shifted hiring odds while white men remain well represented in many areas.
  3. The constructive response is careful rebalancing rather than wholesale rollback: acknowledge and mitigate the harms to invisibly disadvantaged people, and push policies that expand high-quality jobs and create second‑chance pathways so the pie grows instead of people just fighting over slices.

About Being of Two Minds

Technohumanism • 79 implied HN points • 15 Aug 24
📖 Philosophy Consciousness Self-awareness Rationality Modernity History
  1. The shift from Fortune to Reason marks a big change in how people see themselves and the world. People started to believe they could improve themselves instead of just relying on luck.
  2. The rise of new ideas and technology during the Renaissance helped create this sense of self-awareness. It changed how people thought about their place in the world and their ability to impact it.
  3. Even with all the changes, many old ideas and beliefs still linger. Our present largely builds on the past, showing that even with progress, the past isn't completely gone.

Skepticism or Imperfection?

Fake Noûs • 117 implied HN points • 10 Jan 26
📖 Philosophy Religion Epistemology Metaphysics Ethics Logic
  1. Fine-tuning is the strongest argument for an intelligent designer, while the problem of evil is the strongest argument against a perfect God; skeptical theism replies that our limited minds can’t see God’s reasons.
  2. Skeptical theism uses a chess-master analogy: when an expert makes a move you don’t understand, assume there’s a good reason you can’t see; but that analogy is weak because in chess you already know the expert exists and is superior, whereas we don’t have that secure background for God.
  3. A simpler explanation for apparent gratuitous evils is that the creator is imperfect—less than all-powerful or all-knowing—since claiming God is less than all-good doesn’t explain why obvious horrors wouldn’t be prevented.

Yes, Arguments Stand Or Fall Based On Their Merits But The Messenger Still Matters And If You Allow Resentful People Into Your Head, You’ll Be Fooled Into Carrying Their Rage As Your Own

Rob Henderson's Newsletter • 1496 implied HN points • 04 Jun 25
📖 Philosophy Ethics Logic Rhetoric Critical Thinking Dialogue
  1. Arguments should be evaluated based on their strength, but who presents them also matters. It's important to think about the source of the message.
  2. If you let angry or resentful people influence you, you might start to feel their anger too. It's easy to take on emotions that aren’t yours if you’re not careful.

  2. History shows that rebels who defy bans are often celebrated, with real-life examples like the Russian Samizdat and fictional heroes like those in Star Wars and The Matrix.
  3. The moral dilemma of banning things to create ‘proper civilization’ clashes with the concept of individual freedom and audacity, leading to questioning the effectiveness and morality of banning practices.

Essay Club: The Extended Mind by Andy Clark and David Chalmers

Mind & Mythos • 159 implied HN points • 16 Jul 24
📖 Philosophy Cognition Mind Beliefs Cognitive Science Philosophers
  1. The idea of the 'extended mind' suggests that our thinking isn't just in our brains; it includes tools and objects around us. For example, using a calculator isn't just a help; it's part of how we think.
  2. The authors argue that relying on external objects, like notebooks or smartphones, can be essential for forming beliefs and ideas, similar to how we use our memories. This means our minds can extend into the world around us.
  3. While some people disagree with this view, saying real thinking should only happen in our heads, the authors believe that our connections to our environment and the tools we use are important parts of how we think and behave.

The Amoralists

KERFUFFLE • 89 implied HN points • 12 Jan 26
📖 Philosophy Political Philosophy Ethics Legitimacy Authority Social theory
  1. Rulers can replace costly military occupation by creating a moral or religious system that makes people willingly obey, so subjects see submission as divinely right rather than coerced.
  2. When power is perceived as legitimate, control depends more on ideas and beliefs than on force, so political battles shift from armies to priests, philosophers, and demagogues.
  3. Legitimacy makes rule self-sustaining and expansionary because converted subjects will defend and spread the order, but it also makes power vulnerable to ideological attacks and requires continual intellectual work to maintain.

Epistemic Privilege

Fake Noûs • 277 implied HN points • 22 Nov 25
📖 Philosophy Epistemology Ethics Political Philosophy Social theory Identity politics
  1. The idea of 'epistemic privilege' says we should accept testimony from marginalized people about their oppression because they have special access to their own experiences, but treating this as a categorical or novel rule is questionable.
  2. Epistemic judgments are being framed as moral and political judgments, so doubting certain testimonies gets labeled an injustice and turned into a marker of factional loyalty rather than a neutral inquiry.
  3. Politicizing who to believe encourages partisan conformity and biased thinking, which undermines honest truth-seeking and makes solving social problems harder while enabling signaling by ideologues.
