Loevinger's Stages Of Ego Development
Jane Loevinger's stages of ego development 'conceptualize a theory of ego development that was based on Erikson's psychosocial model', as well as on the works of Harry Stack Sullivan, and in which 'the ego was theorized to mature and evolve through stages across the lifespan as a result of a dynamic interaction between the inner self and the outer environment'. Her theory is significant in contributing to the delineation of ego development, which goes beyond fragmentation of trait psychology and looks at personalities as meaningful wholes.
Dr. Susanne Cook-Greuter has further refined both Loevinger's sentence-completion test instrument as well as definitions and distinctions among the stages of ego development.

“I hope I may claim in the present work to have made it probable that the laws of arithmetic are analytic judgments and consequently a priori. Arithmetic thus becomes simply a development of logic, and every proposition of arithmetic a law of logic, albeit a derivative one. To apply arithmetic in the physical sciences is to bring logic to bear on observed facts; calculation becomes deduction.”
—Gottlob Frege (18481925)
