McGinnMind
We know that brains are the de facto causal basis of consciousness, but we
have, it seems, no understanding whatever of how this can be so.

• Physicalist: Describe precisely how consciousness arises from, or is identical to, certain types of physical systems.
• Conscious Realist: Describe precisely how conscious agents construct physical objects and their properties.

Ullman’s SFM Theorem
• The views almost surely have no rigid 3D interpretations.
• If the views have any rigid interpretations, then they almost surely have precisely 2.

Every synchronic perceptual capacity, regardless of modality,
can be described as an instance of a conscious observer.

The conscious perceptual experiences of an agent are a multimodal user interface
between that agent and an objective world.

PinkerHow the Mind Works
We are organisms, not angels, and our minds are organs, not pipelines to the truth. Our minds evolved by natural
selection to solve problems that were life-and-death matters to our ancestors, not
to commune with correctness.

Spin Theorem 1
Every spin transformation corresponds to a unique restricted Lorentz transformation;
conversely every restricted Lorentz transformation corresponds to two spin
transformations, one being the negative of the other.

Spin Theorem 2
Every unitary spin transformation corresponds to a unique proper rotation of S+; conversely every proper rotation of S+ corresponds to two unitary spin transformations, one being the negative of
the other.

The apparent smoothness of space and time are illusions; behind them is a world composed of discrete events, which can
be counted. (p.62)

... the very fabric of space and time is composed of more fundamental spaceless
