The Illegible Real

What Is Called Thinking? • 53 implied HN points • 20 Feb 25
📖 Philosophy Epistemology
  1. Tacit knowledge, or understanding gained from experience, is very important and can't always be explained by rules or theories. It's like how a farmer knows their land or a musician feels the right moment to improvise.
  2. The world often values what can be measured and categorized, but this can miss the deeper, lived knowledge that guides real-life decisions. There's more to learning than just reading books or following formal education.
  3. In a future filled with data and technology, the ability to mix both formal knowledge and experiential wisdom will be really valuable. It's important to recognize the strengths and limitations of both types of knowledge.

Adding Color and Sound to the Tetractys

WaveGuide • 2 HN points • 07 Aug 24
📖 Philosophy Epistemology
  1. The Tetractys is a triangle with ten points that symbolizes harmony and universal relationships in music and nature. Its structure can help us understand connections between numbers, colors, and sounds.
  2. By visually organizing numbers using hexagons, we can see patterns in music and color. For example, numbers that are next to each other in the Tetractys relate to musical intervals like octaves and fifths.
  3. Adding color and sound to the Tetractys creates a deeper understanding of how music and visual art interconnect. This idea suggests that everything in the universe has a rhythm and can be related through these patterns.

Bad Debate, Good Debate and Antidebate

The Joyous Struggle • 59 implied HN points • 13 Dec 22
📖 Philosophy Epistemology
  1. Debates can sometimes escalate into tribal showdowns rather than genuine dialectical processes aimed at uncovering truth.
  2. The current state of discourse is challenged by polarisation, short attention spans, and social media, making traditional debates seem inadequate.
  3. An Antidebate approach blends elements of good debating with dialogical principles, encouraging a reimagining of the purpose of discourse towards generative, collective sense-making.

Pancritical Rationalism: An Extropic Metacontext for Memetic Progress

Extropic Thoughts • 39 implied HN points • 13 Apr 23
📖 Philosophy Epistemology
  1. Pancritical rationalism encourages continuous improvement by embracing criticism and rejecting dogmatism.
  2. PCR aligns with Extropian values, promoting dynamic optimism, self-transformation, and intelligent technology.
  3. A metacontext like PCR can help create an environment for rationality to flourish by fostering open-mindedness and critical thinking.

Finding the third way

The Uncertainty Mindset (soon to become tbd) • 59 implied HN points • 31 May 23
📖 Philosophy Epistemology
  1. There are two common reactions to uncertainty: one is to act like everything is knowable and try to control it, which can lead to poor decisions. The other is to give up and think that nothing can be done about the unknown, which doesn't help either.
  2. Instead of sticking to those two extremes, there's a better approach. It's important to recognize that not-knowing can lead to new ideas and actions.
  3. We can break down uncertainties into different types. Understanding these helps us figure out how to deal with situations where we don't have all the answers.

In Praise of Sheep

The Corbett Report • 23 implied HN points • 08 Jun 25
📖 Philosophy Epistemology
  1. It's often easy to dismiss the masses as 'sheeple', but there might be more to them than just blind obedience. Seeing them as capable of change could inspire hope.
  2. If everyone 'woke up' and became aggressive, it could lead to a new group of tyrants. Instead, we should think of peaceful and creative ways to encourage change.
  3. Being peaceful and cooperative, like sheep, isn’t necessarily a bad thing. It could be a strength that fosters community and understanding rather than conflict.

Neuropessimism, the impossible ideology

Square Circle • 3 implied HN points • 17 Dec 25
📖 Philosophy Epistemology
  1. The brain is a messy, evolved organ whose outputs we admire but that can be self-serving and unreliable, so it’s reasonable to question how much we should trust it.
  2. Neuropessimism says we should reject brain-made judgments and favor the intrinsic value of nature, a stance that pushes toward asceticism and seeking un-simplified complexity but is nearly impossible to fully live out.
  3. The opposite view notes that distrusting the brain may commit a logical error: its convoluted design might be exactly what produces our best insights, so a balanced response is humility, rest, and appreciation rather than total rejection.

Searching for the Root of the Tree of Evil

Nothing Human • 90 implied HN points • 08 Jun 24
📖 Philosophy Epistemology
  1. People want to help solve many problems in the world, but it's hard to choose which one to focus on. Some think we should tackle the root causes rather than just the symptoms of these issues.
  2. The scientific method has helped humanity make big advancements by learning from nature. There are some who believe we need to do the same with our social problems, focusing on understanding how to work together better.
  3. Building better cooperation among people could be the key to solving many of our problems today. We need systems that can help us trust and understand each other on a larger scale.

How we might have viewed the continuum hypothesis as a fundamental axiom necessary for mathematics

Infinitely More • 20 implied HN points • 22 May 25
📖 Philosophy Epistemology
  1. The continuum hypothesis (CH) is about understanding different sizes of infinity, particularly if there's a number between natural numbers and real numbers. Many assume its truth or falsehood is needed for math.
  2. If early mathematicians had been clearer about infinitesimals and different types of numbers, they might have accepted CH as a key part of math and calculus, making hyperreal numbers a standard concept.
  3. Whether CH is true or false is not just a technical question; it reflects deeper philosophical views about the nature of mathematics and how we interpret infinity and set theory.

Letter #16: Separation and Reunion

Charles Eisenstein • 2 implied HN points • 01 Jan 26
📖 Philosophy Epistemology
  1. Standard online formats feel inadequate because ubiquitous AI-generated content makes authentic human communication harder to find.
  2. The scarcity of real connection has grown through the digital age, intensifying people’s longing for genuine, person-to-person exchange.
  3. Some writing is gated behind paywalls, linking access to perceived authenticity with paid subscription models.

Why No Cassandra of Hope?

What Is Called Thinking? • 42 implied HN points • 04 Dec 24
📖 Philosophy Epistemology
  1. Cassandra represents the idea of being ignored while predicting disaster, like prophets in the Bible who warn others but are often mocked or disregarded.
  2. In literature, we see more examples of ignored warnings than of hopeful messages. It seems people find it easier to mock the messengers of doom than to accept hopeful visions.
  3. People who share positive messages often focus on small, gradual changes instead of significant, sudden improvements, which makes their voices less impactful in comparison to doom-laden warnings.

What is Truth (Part 1: Defining Truth)

Ethics Under Construction • 10 implied HN points • 16 Aug 25
📖 Philosophy Epistemology
  1. Truth is all about reasons. It means the explanations we have that help us understand and reduce doubt about things.
  2. Everything has a reason behind it. If something is true, there should always be a solid explanation why it's true.
  3. Understanding truth as just reasons makes it easier to see how everything connects. It’s not some mysterious thing; it’s just about having the right justifications for what we know.

A brief note on Newcomb's problem

Philosophy bear • 28 implied HN points • 02 Mar 25
📖 Philosophy Epistemology
  1. Newcomb's problem involves two boxes: one potentially holds more money than the other based on what an oracle predicts you will choose. Choosing both boxes might seem smart since it guarantees some amount, but there's a deeper philosophical debate about the best strategy.
  2. Some people strongly believe that just picking the blue box (the one with the most potential money) is obviously the best choice, but it's unfair to call those who pick both boxes 'stupid' since their reasoning also makes sense.
  3. Ultimately, this problem raises important questions about decision-making and what it means to want something, suggesting that understanding our desires and decision strategies is complex and varies from person to person.

When the Conceivable Fails

Daniel Pinchbeck’s Newsletter • 10 implied HN points • 09 Aug 25
📖 Philosophy Epistemology
  1. There are many things in the universe that go beyond what we can understand with traditional science. This invites us to think outside the box.
  2. Exploring substances like DMT can change how we see the world, opening our minds to new ideas and possibilities.
  3. Some experts believe there's a deeper purpose to our exploration of these substances, suggesting they could lead us to a greater understanding of life.

Neutrality

Rough Diamonds • 40 implied HN points • 13 Nov 24
📖 Philosophy Epistemology
  1. Neutrality is about treating all opinions equally, which helps people work together despite their differences. It’s important for creating spaces where cooperation can happen without conflict.
  2. Our current systems often lack trust and a shared understanding, making it hard for people to agree on basics. Building new systems of trust is crucial for moving forward.
  3. Institutions need to be more than just neutral; they should create a framework that supports healthy discussions and diverse viewpoints. This way, people can feel both included and understood.

Inferential Appearances

Fake Noûs • 82 implied HN points • 16 Mar 24
📖 Philosophy Epistemology
  1. The post discusses how inferential justification is obtained through appearances.
  2. Explicitly inferring a belief from a premise is highlighted as a method of gaining this justification.
  3. The post is for paid subscribers, with the option to subscribe or sign in for those already subscribed.

Overloading and appropriation

The Uncertainty Mindset (soon to become tbd) • 39 implied HN points • 17 May 23
📖 Philosophy Epistemology
  1. Overloading 'risk' means using the word for many situations that aren't really risky. This can lead to confusion and poor decision-making because we apply the wrong methods to deal with those situations.
  2. Appropriating 'uncertainty' refers to using the term in ways that suggest it can be easily measured or controlled. This misleads us into thinking we can manage all unknowns when some can't be quantified and should be treated differently.
  3. Both overloading and appropriation give us a false sense of comfort. They make scary unknown situations feel more manageable when, in reality, we might be ignoring important nuances.

What is the essential structure of the complex numbers?

Infinitely More • 38 implied HN points • 10 Nov 24
📖 Philosophy Epistemology
  1. There are different ways to think about complex numbers, like focusing on their algebraic or topological structures. Each viewpoint gives us unique insights into how complex numbers behave.
  2. Mathematicians don't all agree on what the essential structure of complex numbers is, leading to multiple interpretations. It shows us that understanding math can be quite flexible.
  3. The paper identifies four main perspectives on complex numbers, which can help clarify the discussions around their nature and engage with broader philosophical questions in mathematics.

The Clouds

Square Circle • 11 implied HN points • 05 Jul 25
📖 Philosophy Epistemology
  1. Trusting words can be tricky. Sometimes, just observing nature, like clouds or the sea, can help solve our mental struggles.
  2. Nature offers a reality that isn't driven by human desires. It allows us to feel something greater than our own thoughts and problems.
  3. By truly engaging with the uncontrived beauty of nature, we can reconnect with a more authentic part of ourselves. There's a sense of kinship with things like clouds that transcends our everyday worries.

What if the Great Filter is complacency?

inexactscience • 19 implied HN points • 20 Oct 23
📖 Philosophy Epistemology
  1. Complacency might be the reason we don't see aliens. Instead of self-destruction, advanced civilizations may just choose to stay comfortable where they are.
  2. Economic reasons for space exploration could fade as the Earth becomes richer. If we make energy and resources abundant, we may not feel the need to explore beyond our planet.
  3. As the human population is expected to decline, the drive for exploration may lessen. With fewer people, our focus might shift to improving life on Earth rather than colonizing new worlds.

In Deeper Darkness

What Is Called Thinking? • 106 implied HN points • 22 May 23
📖 Philosophy Epistemology
  1. Following knowledge may lead to deeper darkness than following action.
  2. The opposite of error is not truth, but another kind of error.
  3. Many traditions emphasize the importance of acknowledging one's own darkness and moving towards an affirmative stance.

Mapping the analogy of institutions as organisms (1)

Space chimp life • 1 HN point • 23 Jul 24
📖 Philosophy Epistemology
  1. Institutions can act like living organisms, but they don't fit neatly into that analogy because humans can belong to multiple institutions and change roles often. This shows that people aren't static and can adapt in many ways.
  2. The way institutions operate can be better understood through concepts from thermodynamics and statistics. This means they can change how they function based on rules and roles assigned to their members, similar to how particles behave in biology.
  3. Institutions perceive the world through their policies and data, rather than physical objects alone. What they 'see' influences their actions and decisions, just like biological organisms react to their environment based on internal processes.

A Short Reflection on Examining

Theory Matters • 1 implied HN point • 02 Jan 26
📖 Philosophy Epistemology
  1. Self-examination is important for growth and moral improvement, pushing us to question life instead of passively accepting it.
  2. Easy shortcuts to knowledge—like AI, quick videos, and the internet—can undermine deep contemplation and make us intellectually and emotionally poorer while also spreading shallow or false ideas.
  3. Too much introspection can be paralyzing, so we need a balance that preserves the difficult work of learning and meaning without falling into harmful overthinking.

What is a "Reason"?

Ethics Under Construction • 15 implied HN points • 08 Feb 25
📖 Philosophy Epistemology
  1. A 'reason' is simply an objective explanation for something. It helps us understand truths by shedding light on unclear ideas.
  2. Objective explanations are thoughts that anyone can understand, giving everyone a similar view of the truth.
  3. To count as a reason, an explanation must be clear, logical, and able to be comprehended by anyone, not just a particular individual.

Utilitarian Naturalism

Mon0’s Substack • 19 implied HN points • 23 May 23
📖 Philosophy Epistemology
  1. Utilitarian naturalism focuses on achieving the greatest good for the most people. It's about making choices that improve overall happiness.
  2. This approach emphasizes the importance of understanding our natural world and using that knowledge to make better decisions.
  3. By combining practical benefits with a naturalistic outlook, we can create a more ethical and fulfilling life for everyone.

Mindwoven Reality

Daniel Pinchbeck’s Newsletter • 16 implied HN points • 31 Dec 24
📖 Philosophy Epistemology
  1. Reality is seen as a unified whole, shaped by our thoughts and consciousness. Our thinking isn't just a reflection, but a force that actively creates our experiences.
  2. Thinking connects us to a shared reality, allowing us to transcend personal feelings. While feelings can divide us, our thoughts unite us in understanding.
  3. Reality is dynamic and evolves with our engagement and consciousness. We don't uncover fixed laws but interact with a living reality that's always changing.

All is Water

What Is Called Thinking? • 80 implied HN points • 13 Feb 23
📖 Philosophy Epistemology
  1. There used to be a quest for a grand theory of everything, but that's less common now.
  2. Philosophy needs to remain tentative and open to falsification.
  3. Different thinkers approach the idea of totalizing theories in various ways, from seeking consensus to celebrating uniqueness.

Epicurus, the First "Rationalist"?

Maximum Truth • 37 implied HN points • 15 Mar 24
📖 Philosophy Epistemology
  1. Epicurus, an ancient philosopher, focused on maximizing pleasure and minimizing pain, inspiring utilitarianism.
  2. Epicurus had a rational and secular approach to understanding the world, advocating for scientific explanations over myths.
  3. He had insightful scientific views for his time, such as proposing the existence of atoms and explaining the origins of scents.

Finite and infinite games

The Jolly Contrarian • 39 implied HN points • 17 Apr 22
📖 Philosophy Epistemology
  1. Carse distinguishes between finite games, which have fixed rules and a clear winner, and infinite games, which have no fixed rules and aim to continue playing without winners or losers.
  2. Infinite games are inclusive and allow for fluid boundaries, while finite games are exclusive and dominate attention while being played.
  3. It's crucial in life to discern when you are involved in finite games aimed at winning, and when you are part of infinite play focused on continuing and evolving.

The Dissolution of "Man"

Daniel Pinchbeck’s Newsletter • 13 implied HN points • 13 Jan 25
🎭️ Culture Epistemology
  1. The concept of 'man' as central to knowledge is relatively new and may no longer be relevant. We're seeing a shift in how we understand ourselves and our place in knowledge systems.
  2. Artificial Intelligence is changing the way we think about knowledge and truth. As AI grows, it challenges the idea that human consciousness is the main source of knowledge.
  3. Our cultural and personal relationships are being affected by this shift. This change is influencing not just how we think, but also our politics and economy.

Yes, Non-Existent Entities Exist (Part 1: The Nature of Abstract Objects)

Ethics Under Construction • 10 implied HN points • 26 Jan 25
📖 Philosophy Epistemology
  1. Abstract objects, like numbers and concepts, can exist independently of physical reality. Even though we can't touch them, they still have a place in our understanding of the world.
  2. Thinking proves our existence, which means thoughts must also exist. You can't doubt your own thinking; without thoughts, you can't claim to exist.
  3. For a thought to count as an objective idea, it needs to be understandable to others. If something is too private or confusing, it isn't a true thought that can be shared.

We're going to be alright

davidj.substack • 11 implied HN points • 07 Nov 24
📖 Philosophy Epistemology
  1. Things are not always what they seem; sometimes we misinterpret situations based on limited information.
  2. Even when it feels like everything is falling apart, there is still hope for a better future if we stay focused.
  3. Justice may take time, but it will eventually prevail, and we must continue to work towards the goals we believe in.

The moral struggle to be a self

Meaningful Particulars • 32 implied HN points • 29 Sep 23
📖 Philosophy Epistemology
  1. The human experience is filled with ambiguous situations that define our struggle for existence and self-discovery.
  2. Values often conflict, leading to moral dilemmas where virtues must be balanced against vices.
  3. The tension between personal freedom and objective reality is essential for growth and success.

How to Learn From What Didn’t Happen

Unfashionable • 30 implied HN points • 10 Oct 23
📖 Philosophy Epistemology
  1. Essays on "how to think" may lack a strict path to truth but offer valuable heuristics.
  2. Reading old books can help broaden perspectives by recognizing implicit assumptions in our worldviews.
  3. Examining intended but unrealized outcomes, as seen in historical examples, can provide valuable insights into complex systems.
