在南澳大利亚，米切尔被人们铭记为阿德莱德大学的重要人物。他对学术生活的贡献是众所周知的:这包括获得大学的资助;成立生物化学主席;在图书馆的收购上花费大量的资金;做出了许多行政上的贡献(在阿德莱德的北阳台上的新哥特式米切尔建筑是以他的名字命名的)。然而，他也是一流的哲学家。他在大学期间发表了他的第一篇论文，之后又出版了两本关于麦克米伦的散漫的书;第一本名为《心智的结构与成长》(1907年)，涉及心智与内容、哲学心理学与神经科学等问题;第二部《头脑的位置》(1933)涵盖了思想和物理学哲学的重叠问题，包括当时相对较新的量子力学领域。第三份手稿《心灵的力量》(The Power of mind)的唯一一份据说在伦敦的炸弹袭击中丢失了。这最后一本书的手稿和作为吉福德系列讲座的最后一篇手稿，至今仍未出版。还有一些较短的论文，包括:《自然与感觉》、《大学与生活》、《教育改革》、《基督教与工业体系》、《生活质量》等，这些都是阿德莱德哈瑟尔印刷公司出版的专著。米切尔还是《头脑杂志》早期版本的定期撰稿人，并定期为《默多克报》(Murdoch paper)撰写篇幅较短的专题文章。《默多克报》是一份颇有名气的报纸。
In South Australia, Mitchell is remembered as an important figure at Adelaide University. He is certainly well-known for his contributions to scholarly life: this included obtaining grants for the University; founding the chair of biochemistry; spending large sums on library acquisitions; making many administrative contributions (the neo-Gothic Mitchell Building on North Terrace in Adelaide is named in his honour). However, he was also a first-rate philosopher. He published his first paper in Mind while still an undergraduate, and later, two discursive and wide-ranging books with MacMillan; the first entitled: Structure and Growth of the Mind (1907) ranged over issues in mind and content, philosophical psychology and neuroscience; the second The Place of Minds (1933) covered issues overlapping mind and the philosophy of physics, including the then relatively new area of quantum mechanics. The only copy of the third manuscript The Power of Mind—part of the trilogy—is said to have been lost during the London bombing raids. There are surviving manuscripts of this last book and proceedings of it as the last in the series of Gifford lectures—none of which, however, have ever reached print. There are also a number of shorter papers including: “Nature and Feeling”, “Universities and Life”, “Reform in Education”, “Christianity and the Industrial System”, “The Quality of Life”, and others, which were published as monographs by the Hassell printing company in Adelaide. Mitchell was also a regular contributor to the early editions of the Mind journal and regularly wrote shorter topical pieces for the Murdoch paper, The Advertiser, when it was a newspaper of some repute.
