Booth's extremely centrist collection of essays is certainly a book of its time (1960s-70s). It is more useful for what it says about the different type of problems facing the University of his era compared to the present time than it is for helping students navigate the intellectual climate of the 2000s. One recurring theme of these essays is Booth's insistence on the importance of rationality alongside other human elements of understanding and decision-making, such as emotional components. Rather than fully exploring how those two elements (and a few others) are tangled together, he hammers hard on the need for rationality without touching on what emotions bring to the table.
Overall I don't recommend this book except to historians looking to breath the cultural air of the 60s-70s, but there were a few take-aways that interested me, even if they weren't earth-shattering or particularly new:
*Beware futurism--a hyper-focus on future outcomes which overlooks the importance and relevance of the present.
*Don't rule out external motives--people want to believe they do research for pure motives like furthering the understanding of humanity, etc. whereas external motives like good grades or pleasing a professor are base. Booth argues that external motives provide the push people need when their pure motives are temporarily if not frequently exhausted.
*There aren't many actual relativists--most people recognize that we are all doomed to partiality, we can't know or see all, and we all have perspectives which are relatively valid. "Relatively" implies some sort of standard by which we can assess differing perspectives, however, so relativism in his sense differs from the extreme "anything goes" type of thing. (He outlines 4 perspectives people bring to the task of, say, interpreting literature: the Dogmatist, the Skeptic, the Eclectic, and the Pluralist.) Seek a common ground on which to discuss and assess positions first.
*Aristotle is still of great use when it comes to critiquing literature.
Great and important book about the need to reconcile reason and values. Gets bogged down by more technical chapters 3/4 of the way through, but the ending is beautiful. MUST read.
