There is no place for dogmas in science. The scientist is free to ask any question,
to seek any evidence, to correct any error ...
Dogmatism has found itself incompatible with the progress of science.

Varimax, a technical term used in factor analysis, currently represents the most popular method of rotating factors to simple structure.

should make you familiar with Varimin. Varimin, presently still a newborn in the overcrowded ward of factorial rotations, is welcomed as providing the top tool for capturing latent structures of variables underlying multivariate interrelations on the phenomenological surface. Its aim is to manifest true complexity and to avoid enforced simplicity.
The downloadable books and papers provide you with a theoretical base. You may practise the program with the help of a user guide and by nine demonstrations of its usages. The essential differences between Varimax and Varimin rotation are summarised here:
| Varimax ... | Varimin ... |
|---|
| ... maximizes variance of factor loadings across factorized variables. |
... minimizes variance of factor loadings across factorized variables. |
| ... does not let variables obtain multiple loadings which is, nearly always, a utopian aim. |
... lets variables obtain multiple loadings which is, nearly always, indispensable. |
| ... facilitates, only seemingly, appropriate factor interpretations. |
... actually facilitates appropriate factor interpretations. |
