Three courses, one framework.
Twenty-seven modules reading mind, perception and design through a single idea: a system has a ground state, everything else is displacement, and displacement costs something to hold.
Every lesson is free to read, in full, right here. The price buys the book and its workbook.

Phronesis Mind
$30Displacement + Coherence
Anxiety, trauma, fear, flow and therapy read as one problem: how far a mind sits from its ground state, and what it is paying to stay there.
10 modules · 54 pages · plus a 7-page workbook
Attention & Consciousness
$99The Gateway to Perception
Attention, prediction, memory, language and insight — the cognitive machinery underneath, treated as ground states and the cost of leaving them.
9 modules · 46 pages · plus a 9-page workbook
Phronesis Design
$20The user's ground state, and what an interface costs
Design as displacement management: what an interface costs the person using it, why glitches read as they do, and how to price the work.
8 modules · 41 pages · plus a 6-page workbook
Phronesis Cheatsheet
$4The displacement framework, on two pages
Every symbol and condition the three courses use, on one printable spread — the notation, the nine conditions, the return-cost law, and how to read anxiety, trauma, flow and burnout in it.

Get the cheatsheet — $4// what this is, and isn't
These read real conditions through a personal working framework. Not peer-reviewed clinical science, not a diagnosis, and not a substitute for one — offered as something to think with. The theory underneath is public and citable at the research, and the same ideas are built into instruments you can run on yourself at the field.
Buying one doesn't lock the others — every lesson of all three stays free to read on the site. The book is for having it in one place, properly typeset, yours to keep.
