Another fairly demanding read from Oxford's Past Masters series repackaged and reissued as a Very Short Introduction. Here it's Ayer's 1980 treatment of David Hume. It's worth noting this because any complaint from beginners about the use of the word 'introduction' should be directed at the publisher rather than the author who I think has done a magnificent job with this beautifully precise study.
Following a short biographical first chapter, Ayer quickly delves into an exposition of Hume's philosophy, focusing on his aims and methods, his assessment of bodies and selves, his analysis of cause and effect, and his thoughts on morals, politics and of course religion. Rather than focusing on a single work at a time, he switches back and forth between the Treatise, the Enquiry, and so on, extracting and assimilating passages seamlessly into his own examination.
Some have complained that Ayer intrudes too heavily with his analysis, shoehorning in too many of his own thoughts and ideas. Personally I didn't have a problem with it. Ayer was an important philosopher in his own right, and it was inevitable that any scholarly treatment of Hume's ideas would include their vulnerabilities and demand interpretation and critique. On balance, I don't think he overstepped the mark.
This may be a short read, but it isn't a light one, and beginners (I count myself as one) should be prepared to concentrate and even make notes to get the most out of it. If you were expecting Hume for Dummies, you'll likely feel overwhelmed and disappointed. It's worth persevering though. I came away with not only a deeper understanding of Hume's own philosophy but also a capacity to actually reflect on the ideas themselves.
