‘Harmony is the common bond of separate thinkers’ (Philolaus). ‘Of the separate thinkers who think together there is, in all rigour, only one example, that is the Trinity’ (Simone Weil) .

‘Aristotle’s definition ‘Thought is the thought of thought’ does not comprehend the Trinity because the noun can equally well be taken in an active or a passive sense. Philolaus’ formula comprehends it because the verb is active’.

Very like Bulgakov Weil argues that God to be active must be Subject and object thought and thought which links them (B’s subject, predicate, copula) but that if he is wholly active the object and the thought must also be in him personal. (In ‘The Pythagorean Doctrine’)

Weil’s Platonic approach to maths, insisting that modern maths wrongly tries to suppress discontinuities and aporias with dubious devices from Leibniz through to standard set-theory is very akin to that of Florensky (and my essay ‘Number and the Between’ in Desmond Festschrift).
