Tan Malaka lost me at telling his readers to see philosophy as sports teams, grouping everyone into idealists vs materialists, where idealism is the bad team and materialism is the good team. This is the kind of reductionistic anti-intellectual thinking that opponents of socialism always point to. The rest of the book just sounds like an essay an average highschooler would write for his finals. Obviously he's a man of action and not really a thinker, so he shouldn't pretend to be. There are no real ideas here, just evidence that people like this should leave the thinking to better qualified individuals. As he admits in the end, clearly the goal of the book is to introduce Indonesians to Western ways of thinking, but it shouldn't be presenting any of this stuff as fact, because that just makes this book a tool of Western imperialism. Especially when it glorifies Europe and never gets anywhere beyond the oversimplified presentation of things they teach in an average highschool. It's also just wrong a lot of the time.
