FROM WIKIPEDIA:
Centrality of Torah – Despite its simultaneous acceptance of both Torah and secular knowledge and culture, Torah Umadda, as a philosophy, prioritises a Torah outlook and knowledge, and in its practice, requires strict adherence to Halakha.
Thus, as far as a secular knowledge, Torah Umadda demands “unquestioned allegiance to the primacy of Torah, and that the apprehension of all other intellectual disciplines must be rooted and viewed through the prism of Torah.”[4] [5]
Similarly, as regards observance of Jewish law: “Not a single fundamental of Judaism has been disturbed by us, we adhere to the same ikkarim (principles of faith), we are loyal to the same Torah, we strive for the same study of Torah and observance of mitzvot that our parents and grandparents before us cherished throughout the generations.” (Norman Lamm, Some Comments on Centrist Orthodoxy.)”
