Reductionism as a Scientific Mythos

The case for narrow utilitarianism

inexactscience • 99 implied HN points • 08 Dec 23
📖 Philosophy Ethics Utilitarianism Critical Thinking Decision-making Moral Philosophy
  1. Utilitarianism is about making choices that increase overall well-being and treats everyone equally. It's a way of thinking that encourages using data and math to improve lives.
  2. While utilitarianism sounds good, taking it too far can lead to poor decisions and people justifying bad behavior. It's important to recognize our own biases and limits.
  3. Narrow utilitarianism suggests we apply these ideas only in clear situations where we understand the problems well. It's better to stay focused and cautious rather than trying to force comparisons between very different choices.

Legacy Shmegacy

David Spinks' Newsletter • 7 implied HN points • 15 Jan 26
📖 Philosophy Existentialism Ethics Mindfulness Identity Values Personal Growth
  1. You can’t control how you’ll be remembered, and the stories people tell are simplified, biased versions of a complex life.
  2. Chasing a memorable legacy twists motives and makes actions about appearance instead of genuinely helping others.
  3. True meaning and legacy come from present-moment micro actions—small loving or unloving choices that quietly ripple outward.

Finite Minds

Fake Noûs • 188 implied HN points • 04 Jan 25
📖 Philosophy Epistemology Metaphysics Ethics Logic Philosophy of Mind
  1. Infinitism in beliefs means you could have an endless chain of reasons for thinking something is true. However, since our minds are limited, it's hard to have a true infinite number of reasons.
  2. Beliefs must be based on more than just potential ideas or past thoughts; they need to be actively supported by real experiences or evidence to count as justified.
  3. Even when considering complex ideas like math or colors, our ability to truly grasp or hold onto those beliefs is still bound by our finite understanding and memory.

Philosophy bear • 78 implied HN points • 27 Jun 25

Living Fossils • 19 implied HN points • 12 Nov 25
📖 Philosophy Cognitive Science Behavioral Economics Moral Philosophy Decision-making Human Psychology
  1. System 1 thinking is quick and automatic, but it can lead to mistakes, especially if we don't take a moment to reflect before making judgments.
  2. People often react based on social cues rather than pure logic, which means they might prioritize fitting in over careful thinking.
  3. Our minds operate with different modules that are activated by specific situations, so we might not always be 'lazy'—we’re just responding to the context we find ourselves in.

The question of socialism posed inescapably in the final moment of the human economy

Philosophy bear • 178 implied HN points • 17 Jan 25
📖 Philosophy Political theory Ethics Social Philosophy Futurism
  1. If AI becomes capable of doing all jobs, humans may only be consumers and possibly owners of capital. This raises questions about the need for human ownership in a fully automated economy.
  2. Arguments for private ownership of productive assets disappear when human labor is no longer relevant. This challenges our traditional views on capitalism and economic roles.
  3. We face a choice between adopting a form of fully automated socialism or continuing an unequal system where a small group owns most resources. Both paths raise important ethical and practical questions.

  3. To achieve peace, we must accept some discomfort and trust that our environment will meet our needs. By doing so, our conflicting desires can come together in harmony.

Ontological Shielding in New-paradigm Research

Charles Eisenstein • 3 implied HN points • 08 Feb 26
📖 Philosophy Ontology Metaphysics Epistemology Consciousness Social Philosophy
  1. Some phenomena seem observer-dependent: the beliefs, intentions, and relationships of experimenters and witnesses can co-create outcomes, so strict replication and detached objectivity may fail.
  2. Ontological shielding is a deliberate research strategy that hides experiments from mainstream scrutiny to create a hospitable reality-bubble where a phenomenon can emerge and mature, with different shielding layers serving different goals.
  3. Forcing new-paradigm results into public proof can destroy both the research and the phenomenon, so careful incubation in protected contexts (even if it invites skeptics, frauds, or secrecy) can let innovations become robust enough to enter wider reality.

Causal Why vs Teleological Why

📖 Philosophy Language Logic Epistemology Metaphysics Cultural Studies
  1. English is not very good at explaining the reasons behind things. It struggles to express deeper meanings behind actions.
  2. Languages like German and Russian might be better for discussing complex philosophical ideas. They offer more clarity in the way they handle 'why' questions.
  3. Understanding different languages can help us see how they shape our thoughts and inquiries about the world around us.

The Economics of Altruism

David Friedman’s Substack • 179 implied HN points • 06 Jan 25
📖 Philosophy Ethics Altruism Economics Evolution Psychology
  1. Altruism can be understood in economic terms by suggesting that people might care about others' well-being as part of their own happiness. This means that helping others can also benefit the helper.
  2. The 'Rotten Kid Theorem' explains that even selfish behavior in children can lead them to act in ways that are good for everyone, as they understand their actions affect their parent's support.
  3. Altruism may have evolved as a way to help groups survive better. When one person helps others, it can create better cooperation for the whole group, making it more successful over time.

Compassion ceilings

Philosophy bear • 214 implied HN points • 17 Nov 24
📖 Philosophy Ethics Social theory Political Philosophy Moral Psychology Public Policy
  1. Some jobs limit how compassionate a person can be. This means people in certain roles cannot show their full kindness because of their job requirements.
  2. If the most compassionate people are excluded from roles, the overall compassion in that group decreases. This can lead to a culture that is less caring and more harsh.
  3. Compassion ceilings can have negative effects, even if the actions causing them aren't seen as wrong. The result is a workplace or society that is less understanding and more likely to harm others.

  1. Religions and ideologies can be seen as having two paths: the right-hand path, typically exoteric and emphasizing external redemption, and the left-hand path, more anarchist and focusing on listening to oneself.

  3. Engaging in left-handed readings of texts involves maintaining the sacredness of the text while exploring unconventional interpretations that may lead to new insights or narratives.

Scott Alexander's "Prison And Crime: Much More Than You Wanted To Know": My Thoughts

Philosophy bear • 200 implied HN points • 28 Nov 24
📖 Philosophy Ethics Utilitarianism Justice Public Policy Social Issues
  1. Prison doesn't seem to effectively reduce crime overall. Instead, we should consider reducing incarceration since it often causes more harm than good.
  2. The costs of imprisonment go beyond just the economic side. They include suffering for prisoners and their families, and even increased crime within prisons.
  3. Even if people feel good about tough on crime policies, a cost-benefit analysis suggests that it's better to invest resources into alternatives to prison that can lead to safer communities.
