I wrote: Fantasy magic and “real” magic are closer than you think. Mathematically speaking, the Kabbalic tree of life is a tree in the same sense as a perk tree in Skyrim where the ontological basis doesn’t necessarily have to describe a vector of reality for prima facie, they are just “empty symbols” where they are given semantic meaning. To say it a different way, you can algorithmically traverse the tree of life whether or not you believe it to be real, so you can deduce that the relations are consistent and formulas derived from those relations are true regardless Read More

## Conservation Laws and Magical and Psychic Energy

I wrote: Gaffluence wrote: Does the first law of Thermodynamics apply to magical energies too? The law being that, energy cannot be created or destroyed, only transformed (simplified version). The answer is no. Conservation of energy is due to a temporal translation invariance, as described in Noether’s theorem and via the Lagrangian. Energy conservation is a consequence of invariance under time translations. Something more abstract than time would not be beholden to that invariance and thus would not be conserved. If it is not physical, it would not be temporal, and if it is not temporal, it is not Read More
