Kisses, Slaps, and Souls

Going Awol • 179 implied HN points • 14 Dec 23

Universes Aren't Real

Outlandish Claims • 59 implied HN points • 30 Apr 24
📖 Philosophy Metaphysics
  1. The concept of universes being 'real' or 'unreal' is not a straightforward matter and cannot be definitively determined.
  2. The framework discussed in the text helps dissolve the age-old metaphysical question of 'Why is there something instead of nothing?'
  3. Existence is viewed as an intersection of infinite universes, each potentially different, which leads to the idea of living in a reality governed by physical laws rather than a simulation.

Logos and Liberty • 59 implied HN points • 20 Apr 24
📖 Philosophy Metaphysics

The Pragmatists Handbook: Transjectivity

Divergent Futures • 2 HN points • 13 Sep 24
📖 Philosophy Metaphysics
  1. Truth isn't just about what's real or what we feel; it comes from how we connect with the world around us. This idea is called transjectivity, showing that understanding comes from our interactions.
  2. The way we categorize things, like calling a chair a 'chair', is influenced by both what we see and how we use it. It's about finding what fits well in our lives, not just what exists independently.
  3. Our views and meanings can change based on our experiences and environment. This means that understanding truth is flexible and evolves as we learn and grow.

Recommended Reading Part IV: Metaphysics

Contemplations on the Tree of Woe • 723 implied HN points • 13 Mar 24

  2. Reading about atheism and counter-atheism can lead to shifts in beliefs, from atheism to agnosticism and questioning physicalism.
  3. Exploring quantum mechanics and consciousness challenges physicalist views and opens up discussions about the mind-body connection and the nature of reality.

"Mary's Room" Is Not a Case Against Physicalism (But Physicalism Still Fails)

Ethics Under Construction • 15 implied HN points • 28 Dec 25
📖 Philosophy Metaphysics
  1. The knowledge argument shows you can know all the physical facts and still not know what an experience is like, so there is an epistemic gap between description and lived experience.
  2. Experiencing something (like red or sweetness) is itself a fact about that property, not an extra mysterious add-on, so leaving out experience misunderstands what those properties are.
  3. Physicalism can reply that the epistemic gap is just a different mode of presentation, but that misses the deeper point that subjective facts are immediate and foundational, so physical explanations are grounded in, rather than fully exhaustive of, experience.

the puzzle without a name

Thicket Forte • 419 implied HN points • 08 Mar 23
📖 Philosophy Metaphysics
  1. Life can feel like a puzzle where you don't have all the pieces or instructions. It's frustrating when things don't fit, and you might feel lost trying to figure it all out.
  2. Real progress comes when you discover new ways to understand or solve your problems. Each new insight can change everything and make life feel more complete.
  3. It's easy to think you've reached the end, but there's always more to explore and understand. Keep questioning and seeking out those hidden pieces, even if it feels challenging.

The assessment of my PhD thesis by the University of Sydney and the way I see our world

Philosophy bear • 214 implied HN points • 25 Feb 25

The surreal line is topologically disconnected—or is it?

Infinitely More • 25 implied HN points • 15 Nov 25
📖 Philosophy Metaphysics
  1. The surreal line can be seen as disconnected based on one way of thinking about connectedness. It's like having gaps that separate parts of a line.
  2. On another hand, if we consider how sets and classes differ, the surreal line appears connected. This means when viewed differently, those gaps can seem to vanish.
  3. Understanding these ideas helps explain why the surreal numbers are unique and fascinating, showing how different perspectives can change our view of mathematics.

The Non Linear Path

The Renaissance Man • 19 implied HN points • 29 Jun 24
📖 Philosophy Metaphysics
  1. Life doesn't always have a clear direction, and that's okay. Embracing the unknown can help you trust your journey, even when it feels scary.
  2. Comparing yourself to others can lead to feelings of jealousy and regret. Remember, everyone is on their own unique path, and you are not better or worse than anyone else.
  3. Holding onto hope is important, even when things don't make sense. It's better to believe that everything will work out in the end than to live in fear.

First ask what it means

David Friedman’s Substack • 269 implied HN points • 13 Dec 24
📖 Philosophy Metaphysics
  1. It's important to first understand what statements about climate change really mean before accepting them as true. Definitions of extreme weather can vary, so the impact of climate change may not be as straightforward as it seems.
  2. When people say healthcare is a human right, it raises questions about what that actually means and whether healthcare workers could be forced to provide care. The term needs clarification to avoid misunderstandings about what rights entail.
  3. Terms like 'living wage' can be vague and subjective. People often think of it as a wage that allows for a comfortable life, but what that looks like varies widely between individuals.

  3. Your sacrifices can define who you are. What you choose to give up can help you focus on what really matters in your life.

Bet On It • 186 implied HN points • 05 Feb 25
📖 Philosophy Metaphysics

  2. The existence of psychophysical laws, like gravity, governs the relationship between mental states and physical states, leading to harmony.
  3. On naturalism, the surprising nature of psychophysical harmony provides evidence against naturalism and potentially in favor of the theory that God exists.

on the meaning of ritual

alice maz • 78 implied HN points • 04 Jul 25
📖 Philosophy Metaphysics
  1. Rituals are practices that help people understand and express important values like kindness and righteousness. They guide behavior and help maintain harmony in society.
  2. Xunzi believed that rituals are not fixed but can be created and adapted over time to meet the needs of society. This shows that traditions can evolve while still being useful.

The Preachers of Death

Bet On It • 171 implied HN points • 12 Feb 25

  3. It’s important to recognize when you're feeling tired of life and not let those who preach despair influence you. Life can be tough, but it's valuable and worth embracing.

storyvoyager • 4 implied HN points • 01 Feb 26
📖 Philosophy Metaphysics

My Own Private Energy Crisis

Justin E. H. Smith's Hinternet • 881 implied HN points • 29 May 23

Finite Minds

Fake Noûs • 188 implied HN points • 04 Jan 25
📖 Philosophy Metaphysics
  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.

Enlightenment as a Reality-Aligned Trance State

  2. When we meditate, it’s not just about being still; it’s about letting our thoughts settle while learning to observe them without rushing to act.
  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 Metaphysics
  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

Breaking Smart • 12 implied HN points • 07 Dec 25
📖 Philosophy Metaphysics

  1. People often see what they expect to see, which can lead them to notice negativity even when it’s not there. This can create a cycle that reinforces their negative beliefs.
