Maimomides was a jewish rabbi and philosopher who tried to bring judaism and philosophy closer together, resulting in him changing both. He tried to make knowledge more accessible to the public and taught to advanced students. In his earlier years, he went to the Andalusian school of Aristotelian studies, where Maimomides was inspired to apply the Aristotelian ideas and science within the Torah.
The earlier writings of Maimomides were mainly about logic and systemization. This doctrine he applied to religion. Later, his interests went to neoplatonism and he got inspired by cosmology. One of his greater works became the Guide for the Perplexed, trying “to enlighten a religious man who has been trained to believe in the truth of our holy Law, who conscientiously fulfills his moral and religious duties, and at the same time has been successful in his philosophical studies”. What I think is the most interesting thing Maimomides did, is putting his belief in God into a logical framework. Through logic and attributes that can be deduced into logic, Maimomides makes an entire proof of God and what exactly He is supposed to be. I think this is interesting, because he was the first jewish philosopher to put something that is transcendent into a mathematical frame.
