On Simple Structure and Factor Analysis

"I had become increasingly unhappy with L. L. Thurstone's principle of so-called simple structure and his widely accepted idea that variables are best explained if based on a minimum number of "factors", on only one "factor" if possible. As far as I can see, varieties in nature are nowhere put on single poles, phenomena generally arise from relations of underlying building blocks, from interaction of components and complex combinations. On all levels of inanimate and animate organization wholes emerge from interweaving parts. I could not understand why factor analysts were doggedly attempting to construe a world of utterly independent "dimensions" and associated constructs in splendid isolation." (David M. Glover)
