A very English book - it begins with the tatoos on a celebrated English football player which turned my stomach immediately (convertit ventrem meum protinus) and doubtless the stomachs of many other Scots. I used the Internet to translate my comment - 'convertit' means 'translated'. Keep that in mind.
Mount then goes on to explain that Latin has "no practical use" - its appeal lies in its snob value, it marked out the student as coming from a superior class, undoubtedly educated in one of England's public schools. Now, I will admit to a loathing for the English public school system and the people it produces, but Mount makes a typical English mistake of assuming that the whole of the UK follows England's model.
In fact, if you go to the Celtic countries to which England still clings as echoes of its Empire, Catholic schools in Ireland and Scotland taught Latin to the working classes, both to those who aspired to become priests (or even nuns) and to those who would remain devoutly lay. It remained a subject with no practical use, but its appeal was not to snob value, it represented a practical career move for those trying to escape poverty ... and it had a role in the continued subjugation of another generation to the tyranny of religion and obeissance to the clergy.
I was taught Latin 60 years ago. I hated it. I was so bad at it I wasn't even allowed to sit my 'O' level. But Mount is correct - he argues that if you've been exposed to Latin teaching at some stage in your childhood, much of the learning will remain with you decades later. Decades later, I thought I might try Latin again - might even pursue the current version of an 'O' level (Latin being the only exam pass I never achieved). I never got round to it ... but I was amazed how much I'd remembered (the Marist Brothers who taught me clearly battered something into me).
Mount's father was an adviser to Thatcher (my profuse apologies for exposing you to that horror), he went to public school, then Oxford, he writes for Tory newspapers and magazines in England, he's related to Cameron, the pig-bothering prime minister, he’s not a man for whom I could find much affection.
The writing in ‘Amo, Amas …’ is pompous and affected. It’s the English upper classes talking down to us proles (as usual). Significantly, he concludes his book with an attack on the Cambridge Latin Course – it’s clearly too proletarian and accessible for the likes of Mount. I’ve found the Cambridge course very helpful and, if you want to learn Latin, I would seriously recommend it as a sound starting point.
Mount, however, recommends “Kennedy’s Latin Primer”. BH Kennedy published his ‘Elementary Latin Primer’ in 1843, a Public School Latin Primer in 1866, and Revised Latin Primer in 1888. It has continued to be revised and revised and revised ... must run to a hundred plus editions by now. Never fear, you can access in online in a range of its 20th century editions - might be worth searching and forming your own opinion. Kennedy's books are the stuff of public schools and clearly were not aimed at us peasants ... or, indeed, at the 21st century.
Mount’s book contains some interesting comments from place to place, and some annoying pomposity too. It’s schoolboy jolly japes … and, yes, if you read it you’ll probably glean some understanding of Latin.
If you are wanting to learn Latin purely because you're seeking to impress (or perhaps even con your way into) the English upper classes - well good luck to you, maybe you'll learn some useful pomposity from Mount as well as a glimmer of Latin.
