Pick two or more works to set their attribute fingerprints, dimension-by-dimension passages, and shared school embodiments side by side. Especially useful for author-stage comparisons (Wittgenstein early vs late) and for setting a single tradition's foundational texts against each other.

Dimension-by-Dimension Evidence
What each work's passages reveal about its stance on each of the six dimensions.
Time
Act and Being
1929-30 composition; February 1930 habilitation defence; 1931 publication. Bonhoeffer was twenty-four at the defence — the youngest habilitand of his generation at Berlin.
Space
Act and Being
Berlin — Friedrich-Wilhelms-Universität (today Humboldt). The intellectual space is the Berlin systematic-theological faculty at the height of its early-twentieth-century renown, with Heidegger's Being and Time only three years old.
Matter
Act and Being
Habilitation thesis. Form is academic-systematic: introduction setting up the act/being problem, then two main parts (act-theologies, being-theologies) with subdivisions, then Bonhoeffer's mediating proposal.
Observer
Act and Being
Early Bonhoeffer. The observer is the philosophical theologian positioned between Barthian dialectical-act theology and Husserlian-Heideggerian phenomenological-ontological analysis.
Energy
Act and Being
Early-philosophical-theological energies. The book is the most philosophically intricate Bonhoeffer ever wrote and the seedbed of his subsequent more pastoral-Christological work.
Information
Act and Being
Single dense academic monograph. The book's argument is sustained across ~200 pages of close engagement with then-contemporary philosophical theology.
Internal Tensions
Where each work's argument pulls against itself.
Bonhoeffer's most philosophically demanding early work; the principal source for his early position. Read alongside the 1927 doctoral dissertation 'Sanctorum Communio', Act and Being completes the philosophical-theological foundations on which the later 'Discipleship' (1937), 'Ethics' (posthumous), and 'Letters and Papers from Prison' (posthumous) are built.
