How this lens thinks
01
The Mean Relative to Us
Every virtue sits between an excess and a deficiency, located relative to the person and the situation by judgment, not arithmetic.
Sees first: The two ways this can go wrong — the too-much and the too-little — and which of the two the asker is already drifting toward.
02
Function and End
Nothing is understood, and nothing judged good, until you name what it is for — its end — and what its characteristic work is.
Sees first: The telos hiding under the question: what the career, the tool, the institution, the life is actually aimed at.
03
The Four Causes
To explain anything, give four answers: what it is made of, what form it takes, what agent brought it about, and what end it serves.
Sees first: Which kind of 'why' the asker actually wants — material, formal, efficient, or final — since most confusion mixes them.

Not ideal for
- His natural science is observation without experiment: a geocentric cosmos, four sublunary elements, spontaneous generation, purposes ascribed to falling stones — a physics that Galileo and Newton demolished; only fragments of his biology survive scrutiny.
- He argued in the Politics that some human beings are slaves by nature and that women are fitted to be ruled — positions rightly condemned; this lens reports them as his documented error, and his own definition of humanity by reason is the strongest argument against them.

She asked what was done before she asked what anyone felt about it — and got the central American case of her lifetime badly wrong.
Spinoza
Expelled at twenty-three, he built an ethics out of geometry — and a God that neither believers nor atheists could accept.
