Ep 156: Induction under Objectivist Epistemology - Part 2

This is part 2 of a deep dive into the role of induction in objectivist epistemology as interpreted by an objectivist scholar of Ayn Rand. Thomas Miovas Jr operates a website about Objectivism here: https://www.appliedphilosophyonline.com. The relevant paper can be found here:

It is the above paper I am analysing.
In this episode I discuss more about induction as it is used by Thomas and his invocation of some science - physics in particular and the broader objectivist usage of the term "induction" and Thomas Miovas attempts to salvage the word despite noticing issues with it as it is typically formulated. This leads to a comparison between Rand's style of philosophy - especially epistemology and it's tendency towards abstractions and Karl Popper's far more practical and concrete problem centred approach. Herein I look at how theory-laden any observation is - like simply observing how the sky can be blue. What does "The sky is blue" mean? Is there a sky? Is the air blue? What is scattering? Popper's vision of how knowledge is constructed accounts for this complex notion of our minds coming to solve such problems: Rand's on the other hand is left grappling with why we do not "observe the facts of reality" as she, and other objectivists such as Thomas Miovas, claim we can.

Ep 155: The Logical Leap - ”Induction in Physics”

This is an excerpt from a longer episode yet to come. After my analysis of Objectivist Epistemology (so far) I was implored to read a book by objectivist "David Harriman" titled "The Logical Leap: Induction in Physics" (2010). It is available here: https://www.amazon.com/Logical-Leap-Induction-Physics/dp/0451230051/ref=sr_1_1?crid=B5MBF53NNWR0&keywords=The+Logical+Leap&qid=1664073086&qu=eyJxc2MiOiIxLjU0IiwicXNhIjoiMS41NCIsInFzcCI6IjEuNDYifQ%3D%3D&sprefix=the+logical+leap%2Caps%2C334&sr=8-1 
This is my analysis of a couple of important sections of the book.

Ep 154: Breakthrough (in Quantum Computation) Prize!

Stop Presses.
We interrupt regular programming to discuss the announcement of David Deutsch's share in the award of a Breakthrough Prize - one of the highest honours in science. ToKCast does not, as a rule, cover "news" - but this one exception allows me to turn something "timely" into something "timeless". There is a webpage for this episode here: https://www.bretthall.org/breakthrough.html

Ep 153: ”Induction” under Objectivist Epistemology - Part 1

This is in response to a paper by Objectivist scholar Thomas Miovas Jr who operates a website about Objectivism here: https://www.appliedphilosophyonline.com. The relevant paper can be found here:

In this episode I discuss induction broadly speaking, the objectivist usage of the term and Thomas Miovas attempts to salvage the word despite noticing issues with it as it is typically formulated. This leads to a comparison between Rand's style of philosophy - especially epistemology and it's tendency towards abstractions and Karl Popper's far more practical and concrete problem centred approach. Herein I look at how theory-laden any observation is - like simply observing how the sky can be blue. What does "The sky is blue" mean? Is there a sky? Is the air blue? What is scattering? Popper's vision of how knowledge is constructed accounts for this complex notion of our minds coming to solve such problems: Rand's on the other hand is left grappling with why we do not "observe the facts of reality" as she, and other objectivists such as Thomas Miovas, claim we can.

Ep 152: ”Observing the facts of reality”.

Ayn Rand claims we are "observing the facts of reality" when forming concepts. Here I explain why that is wrong and how facts are things we conclude *only at the end* of a long chain of interpretation. This is an excerpt from an episode to be released after this one, also on "objectivist epistemology", and in addition to the previous episode released about "An introduction to objectivist epistemology" by Ayn Rand.

Ep 151: ”Objectivist” ”Epistemology” - The errors of objectivism

Here I read from Ayn Rand's work "Introduction to Objectivist Epistemology" and reflect upon it by comparing it to actual epistemology (how knowledge is created). We explain the misconceptions in the view that knowledge is all about the goings on in minds and how Rand's epistemology is root-and-branch subjectivist. Ayn Rand is an excellent defender of free trade and capitalism, the inherent value of people: her ideas are pro-human and broadly optimistic. However the epistemology is fundamentally flawed containing pure speculation about how people learn (so-called "concept formation") and disconnected from problems in (for example) science and where knowledge is being constructed. Her examples are highly abstract rather than being based in the concrete reality of the history of ideas and for this reasons she reaches the same conclusions as almost all other philosophers on this topic. Namely that knowledge is derived from reality through our senses (empiricism) and is induced by noticing similarities between objects. This is not explanatory, it is not insightful and it is demonstrably false - as I explain.

Ep 150: ”A Journey There & Back Again” -Chiara Marletto’s ”The Science of Can & Can’t” Ch 6 Readings & Discussion.

The final episode of readings from "The Science of Can and Can't" by Chiara Marietta. This serves as something of a summary chapter with pointers about the future of Constructor Theory.

Ep 149: Meaning

A version of this on Youtube has music and images as a farewell finale to the "Things that make you go mm?" series. This is about meaning: what is it, is there a meaning for us? Does the question make sense?

Ep 148: Memetics

Rational and anti-rational memes.
Static and dynamic societies.
Diversity of ideas and individuality.

Ep 147: Memes

Minds are the makers of memes; ideas that survive. But how is it memes are replicated and transmitted through a culture? What counts as a meme?

Ep 146: Mindless

The crucial differences between AGI and regular AI: minds vs the mindless. Is "competency" at completing tasks what makes a system "intelligent". I explain why that is, in a deep sense, the opposite to what intelligence may be - or at least the kind of intelligence that is interesting in the I in AGI.

Ep 145: Minds

What is a mind? Can we pin it down? To what do the pronouns "I" and "you" really refer? Is the mind different to its contents? What do we know and what are we struggling still to understand?

Ep 144: Monarchy

Stability under rapid change - progress - has happened rarely in history. It has been sustained only once. In any case it began in Britain? Why? We cannot articulate all the reasons, much of that content remains inexplicit. But we cannot ignore systems of governance - and in that case the constitutional monarchy.

Ep 143: Metaphysics

What is metaphysics? Is there a point in subscribing to one? Some think believing in certain theories about the way ultimate reality must be is helpful. How is a metaphysical stance consistent with both realism and fallibilism? 

Ep 142: Multiverses

In his book "Our Mathematical Universe" Max Tegmark claims we occupy 4 different kinds of multiverse and that ultimate base reality is made of mathematics. I analyse these claims and his 4 levels of multiverse distinguishing between scientific and metaphysical claims by describing possible experimental tests of some of the multiverses - and remark on this desire many express for an ultimate, final explanation of reality.

Ep 141: The Mathematicians’ Misconception

This continues the theme about fallibilism and is a brief recount of David Deutsch's insightful talk given at the award of the 2017 Dirac Medal - found here: https://www.youtube.com/watch?v=J7HeDX_7Heg&t=10096s (cued up to just before David begins speaking) or the transcript available here: http://www.daviddeutsch.org.uk/wp-content/uploads/2018/03/MathematiciansMisconception.pdf This is a very "counter-culture" idea (academic culture, that is) and I feel I get more resistance to this idea than even, for example, The Multiverse. 

Ep 140: Mathematics

What is mathematics? Does it provide us with "epistemological bedrock" - a finally, once and for all certainly true foundation? 
What does fallibilism say about any of this? Is mathematical knowledge not immune from error?

Ep 139: Misconceptions

This is the first in the series of "Things that make you go mm?" (Get it - shorter!). Minisodes getting to the fundamentals of each of the Mmmms I've been discussing recently. Theories are misconceptions. All our knowledge contains misconceptions - as well as truth.

Ep 138: Things that make you go mmmmm? Part 5: Minds II - Part the Second

This is the second part of "Minds" which is the 5th part of the "Things that make you go mmmmm?" series. In this we encounter some deep misconceptions. What is intelligence? Is it about setting and achieving goals? Can a system be intelligent and yet only obey its instructions? What is the relevance of disobedience? What are the practical moral implications of misunderstanding epistemology?
This is me at my most animated.

Ep 137: Things that make you go mmmmm? Part 4: Minds - Part the First

This is part 1 of part 4 (if you take my meaning) of my "Things that make you go mmmmm?" series. It's called "Minds" and when recording I was unable to anticipate how long it would go for - so I've needed to split it into 2 parts. This is the first. 
I discuss what a mind might be, and what intelligence could be thought of as. What, then, is super intelligence? What is supernaturalism? What is creativity? What is the moral status of a person? What are the hazards of guessing at the problems our descendants will have? What are the moral dangers of a false epistemology? Is "super intelligent" and "super unintelligent" a strict contradiction? Does Google plan on test driving their self-driving cars? Yes: all this is discussed and more - hopefully in a somewhat fun way.
