There is, in fact, a paradox about book titles that begin with The Art of..... The word art itself is quite odd. When the word art appears on a school timetable, it means something very specific: the visual arts, involving mainly the creation of things to be looked at. Then there is the broader use of the arts, which includes photography, drama, music, ballet, drama and so on.
It can also be used to describe some apparently mundane practical activity, which is in some way described as tricky, requiring skill, patience or concentration. Papering a wall, for example could be so described.
It does not stop there. The word 'art' can be used to mean 'a skill'. So you can have a book called The art of war, or, indeed, the art of persuasion.
Going further are the 'dark arts', sinister, devilish skills. These include a politician's ability to remove a political rival without anyone knowing he did anything or, even if they suspect finding out how it was done.
So the word art has a very wide range of usage. You can see this very well set out in the Cambridge English Dictionary:-
This range should not be surprising. The word art is derived from the Latin word ars, meaning, of course, art. The Roman poet of the Late 1st century BCE to early 1st century CE composed poem called Ars Poetica, normally (and rightly) translated The Art of Poetry. In it he makes the famous statement:-
"Ars est celare artem" or *the art lies in concealing the art (ie the skill which created the art).
Perhaps it would be better to translate it as
The skill lies in concealing the skill.
A contemporary of Horace, Publius Ovidius Naso (Ovid), was exiled by the emperor Augustus, allegedly for publishing a didactic poem called ars amatoria or the art of love. This account of how to seduce married women was supposed to be tongue-in-cheek, but fell foul foul of Augustus' morality legislation. But it was certainly a 'How To' poem.
What comes from all of this is that the use of the word art is essentially contextual. A writer needs to make sure that a particular intended meaning is clear from the context.
