Discussion on: Private methods are a code smell

private methods don't actually hide logic.

They usually do though, which is (in my experience) the main reason for them to be private (which this post details).

I generally don't think class are required for most logic, they should generally be free functions which operate on the class/data. This way your class keeps its single responsibility and you have functions with one responsibility.

Neither do I, it heavily depends on the language you're using. A lot of languages don't require you to use classes to encapsulate logic. Using classes actually enables the use of private logic. Using functional approaches leads to treating each function as a valid public entity, generally leading to less running into the "private code smell".
