Maimonides Quotes
Know that the difficulties which lead to confusion in the question what is the purpose of the Universe or of any of its parts, arise from two causes: first, man has an erroneous idea of himself, and believes that the whole world exists only for his sake; secondly, he is ignorant both about the nature of the sublunary world, and about the Creator's intention to give existence to all beings whose existence is possible, because existence is undoubtedly good.
Maimonides, Moses. The Guide for the Perplexed. Translated by M. Friedländer, 2nd ed., George Routledge & Sons, 1904, p. 272.
Moses ben Maimon (1138–1204), commonly known as Maimonides and also referred to by the acronym Rambam, was a medieval Sephardic Jewish philosopher who became one of the most prolific and influential Torah scholars of the Middle Ages. In his time, he was also a preeminent astronomer and physician, serving as the personal physician of Saladin. Born in Córdoba, Almoravid Empire (present-day Spain) on Passover eve, 1138 (or 1135), he worked as a rabbi, physician and philosopher in Morocco and Egypt. He died in Egypt on 12 December 1204, whence his body was taken to the lower Galilee and buried in Tiberias.
