Aliocha's reading technique for dense philosophy

Post by Aliocha (@4liocha_), 2026-10-24

What it is, and who made it

This is a reading method for dense philosophical texts, shown on Thomas Aquinas, Summa Theologiae I, question 2, articles 1 to 3. Aliocha learned it in a course she names, "Leitura e interpretação de textos clássicos". She uses it only for reading that will be assessed academically. In her words, without it she would read "2 livros por ano".

The post is the method, and the four images show it in use:

  1. a notebook page that rewrites two objections as numbered premises and conclusions;
  2. 2. to 4. the printed page, annotated with circled conjunctions, colour highlights, cut marks and margin brackets.

Parts, layer by layer

The method, as stated (observed in the text).

  1. Structure. Split each argument into premises and conclusions, and often presuppositions.
  2. Movements. Decide whether arguments form a chain, a list (number them), or a turn, where the author moves from affirmative to negative.
  3. Conjunctions. They "indicate reversal of movement or continuity": they deny or confirm what came before.
  4. Active reading. Underline the main argument and the links between ideas. The aim is to reproduce the author's whole movement from conclusion to conclusion.

The notation, layer by layer.

LayerPartProperties (label)
L1 notebook (image 1)ruled page in a tablet notes app27 ruled rows at pitch 0.0289 of the height (M); labels P, C, pressuposto, 1º momento, 2º momento, numbered premises (O); yellow behind the labels (O)
L2 printed page (images 2 to 4)two columnsLatin original on the left, Portuguese on the right (O)
L3 colour code (images 3 and 4)highlighter inksyellow #c7bc75, blue #7eaed3, purple #875fa3, and teal #35555b where blue lies over yellow (M); yellow covers 0.255 and 0.398 of the two annotated columns (M)
L3 role mappingwhat each colour meansyellow is the first premise or proposition, blue the second premise or presupposition, purple the conclusion or objection (O). Purple marks a conclusion on page 164 and an objection on page 165, so colour codes a role within the current movement, not one global role (I)
L4 cut and circle marksI-beams, circles, bracketsI-beam bars split segments; 7 of them in objections 1 to 3 of article 2 (O, counted). Circled: portanto, mas, pois, nem, ora, assim (O). Margin labels: P¹, P², C, Pressuposto, 1 movimento, 2º movimento, Objeção, Corolário, Início do 2º (O)
marginaliawritten rules"As conjunções indicam mudança de movimento"; "Corolário. Conclusão acessória a outra conclusão"; "Estrutura diferente de tudo até agora" (O)

The argument under the notation. Each objection in article 2 has a fixed shape: a major premise, then Ora (Latin Sed) introducing the minor premise, then Logo (Latin Ergo) introducing the conclusion. Objection 3 nests: its minor premise is itself argued ("finite and infinite have no proportion") before the conclusion.

Text measures of her post (code).

The framework behind it

An argument has a grammar, and connectives are its function words. The method makes three structures visible:

The colour, the cuts and the brackets are three encodings of the same tree, one per layer of attention. Reading actively means rebuilding that tree.
