First published in 1917, A Study of Numbers is a deeply-philosophical account of the living, universal, qualitative, and casual reality of numbers as they are expressed throughout the cosmos and nature. Beginning from what he refers to as 'the irreducible one', Schwaller deals with the unfolding of creation via the cycles of polarization, ideation, and formation. Topics covered include: numbers, values, and relations; the disengagement of numbers; the harmonic basis of numbers; the development of values; and the establishment of harmony.
