One of the major points of the article is the "no True OO Programmer" fallacy:

this is my experience whenever I argue against Object Oriented Programming (OOP): no matter what evidence I bring up for consideration, it is dismissed as irrelevant. If I complain that Java is verbose, I’m told that True OOP Programmers let the IDE take care of some of the boilerplate, or perhaps I am told that Scala is better. If I complain that Scala involves too much ceremony, I’m told that Ruby lacks ceremony. If I complain about the dangers of monkey-patching in Ruby, I’m told that True OOP Programmers know how to use the meta-programming to their advantage, and if I can’t do it then I am simply incompetent. I should use a language that is more pure, or a language that is more practical, I should use a language that has compile-time static data-type checking, or I should use a language that gives me the freedom of dynamic typing. If I complain about bugginess, I’m told that those specific bugs have been fixed in the new version, why haven’t I upgraded, or I’m told there is a common workaround, and I’m an idiot if I didn’t know about it. If I complain that the most popular framework is bloated, I’m told that no one uses that framework any more. No True OOP Programmer ever does whatever it is that I’m complaining about.

One really big problem with how your argument is structured is that you cherry pick warts from OO languages, while at the same time cherry picking good solutions from FP languages.

It would be quite simple to turn the argument around by doing the exact opposite thing - cherrypicking nice things from OO languages and warts from FP languages and then use the same argument about scotsmen in the other direction.

Arguments about whole categories of languages when not limiting yourself to least common denominators end up stupid pretty fast as it is always possible to find one example or another that fit the point you want to claim.

[geoelectric]

This was my take as well. As many good points as there are in the article (and there are many), the whole thing is "No True Scotsman" itself.

Any attempt to fuse aspects of other languages or paradigms with OOP in order to mitigate the listed problems are dismissed as "not OOP" to serve the purpose of illustrating that OOP sucks.

My experience is that any pure paradigm has limited context in which it's ideal and many pitfalls outside that context. OOP is no different. Foolish adherence to consistency, hobgoblin of little minds, etc.

Where I will agree, at least in spirit, is that OOP has a few different aspects, including the implementation in a given language, the current understanding of best practices for a given context, and the cult of context-independent "design correctness". That last one has major issues.

When the cult drives the implementation, you get high-ceremony languages like Java. And when the cult drives best practices, you get maintenance issues like those currently being acknowledged around invasive unit testing, etc.

The key there isn't the design paradigm, IMO, but the fallacy of trying to apply a best practice without understanding why it's useful or analyzing whether it's the right thing to do for the current situation.

An analogy would be normalizing a relational database. There's a "correct way" to do it, which in theory reduces maintenance if you go to third+ normal form. In practice, knowing when to relax normalization is the difference between success and a mess. So goes DRY, SOLID, etc.

This is nitpicking and is entirely irrelevant to the topic at hand; but you said OO (to refer to object-oriented) and FP (to refer to functional programming). You should have either stuck with OO and F, or OOP and FP.

I'll sink back into the corner now....

[zorbo]

The article pulls a Fallacy fallacy, otherwise known as an "argument from fallacy". Basically what he says is "none of the arguments against me are correct, because fallacy X". I simply ignore such statements, because they make discussion impossible.

[chriswarbo]

You're committing a fallacy fallacy fallacy:

> Above, I have, with some humor, suggested that proponents of OOP tend to indulge the No True Scottsman fallacy when arguing for OOP. On a more serious note, some proponents of OOP might try to defend themselves by suggesting that we are facing issues of commensurability: proponents of the pure-logic paradigm, or the functional paradigm, or the OOP paradigm, talk past each other because we can not understand the axioms on which each other’s arguments rest.

> I am willing to believe that this issue explains some of the disconnect between some of the more thoughtful proponents of the different styles. And yet, there has to be something more going on, since the empirical evidence is so overwhelmingly against OOP. Proponents of OOP are arguing against reality itself, and they continue to do so, year after year, with an inflexibility that must have either non-rational or cynically financial sources.

[chris_wot]

Oh, so what happens if all the arguments against him are actually fallacious? You realise that you would have ignored him based on the fallacy of the Fallacy fallacy?

[zorbo]

No, I wouldn't have. I ignore his claim that all arguments against him are True Scotsman Fallacies. I don't ignore the actual arguments against him, nor the one he makes. Any of those arguments may or may not be fallacious themselves, but that has no bearing on me ignoring his claim that they all are.

[chris_wot]

What I'm saying is that if all the arguments against him were True Scotsman Fallacies, then it would be fallacious to ignore him based on a mistaken understanding that he is arguing based on a Fallacy fallacy. And as we all know, no true logician would make such a mistake.

[zorbo]

I think you misunderstand me, or I you. I'm not ignoring him. The only part I'm ignoring is his claim that all counter-arguments made against him are True Scotsman Fallacies. And I was right to do so, since apparently later in the article he revealed it as a joke.

[peterashford]

I suspect you're all about to disappear up your reducto-ad-absurdum

[mcphage]

That's not really the No True Scottsman falacy, though. A NTSF would be something like:

A: Java is too verbose.

B: Java isn't really a OOP language.

This is more like:

A: Java is too verbose.

B: Sure, but that's a statement about Java, not a statement about OOP.

If you list a bunch of criticisms of OOP languages, that doesn't mean that those criticisms automatically become criticisms of OOP as a concept, merely those of the languages themselves. Especially when you can find OOP languages that don't match that criticism. Java is verbose, yes. But it doesn't mean OOP languages are verbose (what the article author would like to claim), and it doesn't mean that Java isn't an OOP language (what the author believes other people use to deflect the criticism). It means that Java is verbose.

[davelnewton]

The same goes the opposite direction, though. While I'm sure your actual arguments are more cogent, simply complaining about something specific isn't an argument against OOP in general.

And I doubt that anybody claims Java isn't verbose, or that the IDE "handles" it--regardless of who's doing the typing, Java is verbose. The only people that hold up Java as a good example of OOP are people that don't really know any other version.

[tpresa]

He does argue that OOP introduces complexity without any unique strengths.

[davelnewton]

Are you referring to the OP's post? That part of it is simply incorrect. If you're referring to the comment I replied to, I don't see this argument in there.

[andybak]

I think there is a similar flaw in your argument as follows.

You: OO is flawed because of x

Me: But OO language a doesn't have a problem with x

You: Ah but language a has problems with y

Me: Yes but language b doesn't

etc...

You conclude OO is inherently flawed

I conclude that there are now languages without flaws...

[blowski]

Exactly. If you look for a language without flaws, you may as well give up programming.

On the other hand, if you say "I'm trying to do X - what's a good language to use?" then we can have a conversation. Some of the flaws are irrelevant in some projects, but roadblocks in others.

Debating the pros and cons of languages without the context of a project is like discussing the best form of transport without having any idea of the journey.
