I attended St. John's College's Graduate Institute, spending four summers (8 weeks each) reading and discussing a shorter version of the undergraduate reading list, and took an M.A. degree in the Liberal Arts thirty years after my Computer Science degree. It was well worth it for me, at age 54, and for participants who were retirement age. At 40 you may be feel less smart than when you were younger, but you're very likely more mature and a better reader. St. John's offers week-long Summer Classics sessions, which convey a lot of the same experiences of reading and discussion: https://www.sjc.edu/santa-fe/programs/summer-classics https://www.sjc.edu/santa-fe/programs/summer-classics
