We are witnessing the emergence of a physical classification of galaxies. New methods of inquiry, including multivariate statistical analysis of galaxy manifolds, scaling laws and correlations provide important clues towards understanding the formative mechanisms and evolutionary histories of galaxies. Galaxies of different families form two-dimensional sequences in the parameter spaces of their many (but not all) global observable properties; this relative simplicity probably reflects the regularities and feedbacks in the processes of galaxy formation. A minimal three-dimensional parameter space, whose axes include measures of galaxy size, density, and kinetic temperature promises to become the equivalent of an H-R diagram for galaxies.
