CURRENT Companion
The thinkers.
45 names the book leans on, across philosophy, psychology, critical thinking and management theory.
Each entry is short on purpose: what they argued, the one work worth starting with, and where their thinking resists CURRENT's. Nobody here agrees with the book entirely, and that is the point.
Greek philosophy
- Heraclitusc. 535 – c. 475 BCE
The river is his. Read as process philosophy rather than aphorism, Heraclitus claims that things are patterns of change rather than objects that happen to move — the reversal the whole book rests on.
The River
- Aristotle384 – 322 BCE
Phronesis — practical wisdom — is knowing what this situation asks, which no rule can supply in advance. The oldest statement of the book's account of judgement.
Shape
Moral philosophy
- Mary Midgley1919 – 2018
Midgley's lifelong argument was against single explanatory pictures — the myths we adopt without noticing they are myths.
The River
- Alasdair MacIntyre1929 – 2025
Supplies the word the book leans on: practice, with standards internal to it — and the warning that institutions reliably corrode those standards in pursuit of external reward.
Shape · The Practice
Organisational learning
- Chris Argyris1923 – 2013
Espoused theory against theory-in-use names the gap precisely; double-loop learning asks whether the governing variable, not the tactic, was wrong.
Sense · Shape
- Peter Sengeb. 1947
The learning organisation, stripped of caricature, is concrete: forums where disconfirming information travels upward without cost.
The Practice
Philosophy of science
- Karl Popper1902 – 1994
Ask what evidence would change your mind before the evidence arrives. It is the cheapest available discipline against premature certainty.
Stay · The Practice
- Michael Polanyi1891 – 1976
We know more than we can tell. Tacit knowing accounts for what a practitioner sees but cannot yet articulate — the knowledge that arrives as unease before it arrives as words.
