【材料一】

——摘编自罗素《西方哲学史》

【材料二】“政体”这个名词的意义相当于“公务团体”，而公务团体即是每一城邦“最高治权的执行者”，最高治权的执行者可以是一人，也可以是少数人，又可以是多数人。……政体（政府）以一人为统治者，凡能照顾全邦人民利益的，通常就称为“王制（君主政体）”。凡是政体以少数人，虽不止一人而又不是多数人，为统治者，则称“贵族（贤能）政体”。……以群众为统治者而能够照顾到全邦人民公益的，人们称它为“共和政体”。……僭主政体以一人为治，凡所设施也以他个人的利益为依托；寡头（少数）政体以富户的利益为依托；平民政体则以穷人的利益为依托。三者都不考虑城邦全体公民的利益。

——亚里士多德《政治学》

【材料三】吾爱吾师，吾更爱真理。

——亚里士多德

据材料一，指出亚里士多德在科学领域取得的成就。
