And I'm noting this is not an argument about 'want', but what 'is'. — Philosophim

What is a woman? — BenMcLean

You are both asking for dogma which runs the risk of invalidating and erasing transgender persons.

Dogma is authoritative – as if only it is the truth – as if identification by others should supersede self-identification.

The experiences of transgender persons tell us that the definition of “woman” or “man” cannot be based solely on the physical body at birth.

I am more a skeptic than a dogmatist, encouraging open-mindedness and questioning rather than stifling them.

1. A man is an adult human male.
2. A trans man is not an adult human male.
3. Therefore a trans man is not a man.

(The same pattern for "woman," and interpreting "male" biologically.)

Nobody disputes this argument's validity, but validity is not sufficient for philosophical substance in a contested debate. — Jamal

At least we agree the argument is valid.

Of course, what you have actually done is attempted to sidestep the central dispute, which is over whether or not your definition is correct. Your conclusion follows only because you have already made it inevitable by assuming the centrally contested definition. — Jamal

No Jamal. My conclusion follows because I have multiple true premises. No begging required. All you have to demonstrate to invalidate the argument is whether the default definition of man or woman is biological, or a role.

Now, had you taken the time to defend the definition, none of this would matter. Perhaps you just wanted to set things out clearly and simply, and what could be wrong with that? But the following is all you offered in defence:

Most of the world does not view man and woman by gender, but by sex, so the default goes to sex.
— Philosophim

This is where you need a good argument—where it's difficult.

Feel free to point out where its flawed. Your judgement of whether the argument is 'good' or not is only evidenced by your ability to refute it.

This is better: you beg the question when your premises assume the truth of

the conclusion. And I think your argument does that, not explicitly but in the context of the ongoing debate. Premise 1 presupposes the conclusion by fixing the meaning of "man" in a way that already excludes trans men. The conclusion is assumed rather than argued for. — Jamal

I think you've put forth a good effort, but couldn't be more wrong here. You see, we also have to establish what 'trans X' means as well. We need the definition of X, trans X, and the conclusion of whether trans X is X. By fact the definition of X alone cannot assume the truth of the conclusion. Sorry Jamal, its impossible for this to be begging the question. You're going to have to dispute the definition of X, or trans X.

In reality, begging the question takes different forms: assuming a disputed claim, building the conclusion into a definitional premise, or stipulating a definition that can only be accepted by someone who already agrees with the conclusion. Some philosophers have made the distinction between intrinsic and dialectical question-begging. In those terms, you have done the latter. — Jamal

This sounds like you're trying to avoid disputing the definition at this point by trying to twist the clear term of question begging. Not buying it. Dispute the definition, or take another approach. Otherwise I have a logically sound argument.

If you have a particular argument against the OP, it is your job to point it out and explain why it counters the premises or conclusion of the OP. If there is a particular debate that you feel is worth pulling in to address the claims of the OP, feel free. But a general reference to unspecified arguments without any demonstrable link to the OP is something I can rationally ignore.
— Philosophim

If you just want to win, then sure. But if you want to find truth, then no, you cannot ignore the chance of attaining knowledge. I pointed you in the direction of a respected philosophical authority (the SEP), and mentioned that some thinkers regard man and woman as cluster concepts. I assumed, because you hadn't mentioned anything remotely like that, that you were unaware of all the work that has already been done in the field. — Jamal

I did read it. But I did that for my own curiosity. That doesn't invalidate my point that it was a flawed counter in any argument. Throwing a massive amount of information at someone without pointing out its specific relevance to the discussion is not a viable tactic from someone trying to find the truth. If you had simply mentioned, "Hey, here's some reading on gender. Its not an argument against what you've written here, just some information if you're curious," I can see your point. But you wanted to win the argument, not just give me knowledge. That information not existing in my argument did not mean the argument was flawed. Claiming that was your mistake.

I meant to call your statement that sex is the default into doubt, to push back against it with examples. If social position is operative in society in substantial, non-ephemeral ways—and I gave examples—then it shows there is a burden on you to support your statement that sex is the default. It does not rigorously prove that sex is not the default, but I had no intention of doing that. — Jamal

This is more interesting now because we're discussing the issue proper. The problem for you is that I did assert that sex is the default reference for man and woman. So if you can't prove that the default is something else my position holds.

The thing is, you are not merely saying, "Given my definition, trans women are not women." (Everyone agrees with this). — Jamal

Correct, because it is not my definition. It is the default definition that people assume when man or woman is unmodified in English.

You are also saying that your definition is the default, and that rival definitions, and therefore contrary conclusions, are deviations from correct usage. At this point, the masses are functioning as an authority. — Jamal

You are free any time to demonstrate that when most people see man and woman unmodified that they instantly jump to it being a role and not a sex reference. Go tell a random person on the street, "I saw a woman walking through the woods the other day." After some time then ask them, "When I said "woman" did you think adult human female or adult human male?" You and I both know the answer to this. So we can stop pretending otherwise. Free of specific context, woman and man default to a sex reference, not a role. To be clear, its the default of the unmodified term. Its not that man or woman can't mean role, they just need proper modification and context to clearly convey that.

How do you get to that? The logic surely goes like this:

Most people use "man" and "woman" to refer to sex, not gender.
Therefore "man" and "women" refer to sex, not gender.

There is a missing premise there — Jamal

Yes, this is fair criticism and I hope the discussion focusses on this rather than the above disputes. Language is a series of signs within context that indicate concepts. But they do follow default definitions within the language they are a part of. For example, black and white are colors without any modification. But we can modify default definitions to create more 'colorful' language. For example, I can call someone a 'white' man. We all understand this is a reference to race, and that a person's skin doesn't have to actually be the color white, but ethnicity or even social class. "Bob might have dark skin, but he's really a white man underneath it all."

Metaphors and similes are also tools to modify language into interesting comparisons. "Todd is just like a black man". Todd of course would be categorized as a 'white man' in reality, as he does not have any black skin or 'ethnicity'. Its a simile where we attribute behavior to ethnicity. Which is fine, but does the behavior make the ethnicity, or is it a trait that is sometimes associated with the ethnicity? Its the later.

It would then be a far cry to say by default, "Tom is black" when he is actually white by ethnicity. Even in a context, there is a default meaning for the term. We understand the default for 'black' is ethnicity, not the actions associated with the ethnicity. So if Tom, a white man, decided to apply for black scholarships, we would rightly deny Tom the ability to do so because 'white' is by default in this context ethnicity, not behavior. Do you disagree with this?

Remove the context, and the base meaning of white as a color still applies. All of this is very important, because if the default is misunderstood, everything built off of it becomes confused. If you started saying, "White unmodified can also mean the feeling of being white", it becomes very difficult to understand language without further context. "Tom is a white man" now all of the sudden becomes ambiguous. Do we mean Tom is white by ethnicity or is actually black by ethnicity and feels white? Suddenly a "White scholarship" can be applied to not be the default meaning, which was ethnicity, but has become unnecessarily ambiguous. Language is now confused, people don't know what it means anymore and thus language has become worse.

Defaults generally happen in languages to avoid ambiguity and create efficient discussion. No one wants to speak to another person saying, "A woman with x sized hips, medium breasts who feels like a male..." People just denote, "A woman" and English speakers understand 'woman' to refer to 'sex' by default. Its just an efficient word to describe a basic concept unambiguously. A "White woman" would default to an ethnic description of a woman by sex. A word that does not have a default is confused and awful in correct language, as language's goal is to accurately communicate a concept efficiently to another person. So the idea of a default for nouns is not flawed, its a real phenomenon in any good language.

The language as well can often tell us what the default is. Lets look at the etymology of the terms man and woman. First, we understand they, in context with each other, were originally sex references. Gender, the idea that males and females have sociological expectations placed upon them, needs a reference to the sex itself. "Male gender" is the sociological expectation placed on an adult human male. Eventually, people started using "Man" as a simile or metaphor. "He acts like a woman." "He's such a woman." But the simile and metaphors don't actually imply the person is 'the other thing', its an implication of traits that are often associated with the thing, in this case behavior.

You can probably see by this point in your reading why I did not go in depth on the OP. My experience is that long posts do not keep the attention span or conversation going. I have found it best to save more in depth assertions for those who are interested in exploring them. I'll continue now.

Back to simile and metaphor. Proper simile's and metaphor's do not imply the person is the default use of the simile and/or metaphor. "My brother Tom doesn't stop talking when he drives. He's such a parrot". We can glean from the context of the sentence that most likely, him being a parrot is a metaphor, not an actual driving parrot. :) The default for parrot is again, the bird. Even though we could parrot other people who use parrot in different ways. As you can see, despite the different meanings of the term parrot in the sentence, you were able to easily understand what was stated without ambiguity. That's an effective and clear sentence.

So, now back to "Trans men are men". The "Are men" is where we will focus first. Is it a metaphor? Is it a claim to be an actual parrot? We'll need to look at what a 'trans man' is first. 'Trans' generally means 'to travel across' and 'man' generally means a sex referent unmodified. But here we have a modification. Intuitively we would think, "Oh, that's a man by sex who is crossing over to the other sex." But of course the phrase was not built on common English expectations.

Instead, we actually need to add some more specificity. Man can also mean 'gender role' in particular contexts, but the context needs to be clear. So we should probably add a modifier to make that clearer. "Trans gender man". This clarifies that the 'man' in question is not a man by sex reference, but by gender reference. And since its 'trans', or crossing over, we can assume their default gender would be woman. And a default gender applies to a default sex. So the trans gender man is a woman. Just like my parrot example above, we can glean from the full sentence the accuracy of the situation. This is a woman who believes in following the sociological expectations of others about sex. She does not want to follow the role society expects of her, she wants to follow the role society expects of men again. Unlike some who would simply reject societal expectations, she embraces them for the other sex.

If the philosophical goal of language is to clearly communicate ideas accurately (and we like efficiency too), has the above accurately conveyed the situation? I would say so. There's no ambiguity. But lets look at the original phrase in question again.

"Trans men are men". What does this mean? Trans men could denote trans sexual or trans gender, so it probably needs a little clarity there. But lets assume its just gender, and there is no transitioning of sex features in any way. "Trans gender man" is a complete phrase that indicates that this is a woman who is taking on the sociological expected role of the other sex. So what's the purpose of the latter addition? If 'man' unmodified by default means 'male sex', this is obviously false.

The modifiers of men further convey the point that man, unmodified by default, refers to sex. This confusion was obviously apparent when the phrase 'trans man' defined common English expectations. For example, most people think on hearing the phrase for the first time that 'trans man' means "A man who's transitioned". There needed to be clarity about the separation of sex and gender with the terms man and woman. Thus the term 'cis' was used to modify the default term so that you would understand that man or woman in this instance refers to gender, not sex. A cis woman, is a woman who has the female gender. This is a clear and accurate sentence.

The proper tautology for accurate and unambiguous communication should be "Trans men are trans men" Or "trans men are not cis men". But "Trans men are men" is ambiguous and poorly phrased at best, or wrong at its worst. Thus the phrase is simply confusing. Assuming that someone is trying to communicate accurately and efficiently the true intentions behind the phrase, they should modify it to be more clear. "Trans men are adult human females that take on the gender role of men" No question there, but wordy. "Trans men are women" still conveys the same information accurrately and more compactly. "Trans men are the male gender" is also compact, but might want to clarify if they're using gender as the sociological meaning vs sex synonym.

As philosophers or people who study philosophy, rationally we should embrace clarity of language and thought where possible. We understand that politics, religion, and ideologies use and abuse language to manipulate and control the populace. This is in defiance of understanding the world and reality in a clear way. So if the phrase is ambiguous because people are going to default to thinking 'Trans men are men' means 'Trans men are men by sex", there shouldn't be a single problem with clarifying the phrase to be clear in its intent.

The only reason I can think that a person would be against it is if they're intending to conflate the default term with gender to avoid having to address the fact that cross gender people aren't cross sex. But you wouldn't be one of those would you? I would assume having studied philosophy for years that you would be aware of such basic deceptions and manipulations. Clarity of language and thoughts is paramount to the study, so why use unclear language? The use of language for conflation or manipulation is the antithesis of philosophy.

My apologies for giving you a mouthful of words (but not a literal mouthful, we both know that right?) but I was saving such extensive explanations for those who would address the subject more pointedly and not reactionary. Please take your time to respond, I will not view time taken to mean anything other than you are thinking about it and you'll respond when you have time.

You are both asking for dogma which runs the risk of invalidating and erasing transgender persons. — Questioner

Transgender persons do not exist. The very term "transgender" is an anti-concept.

This doesn't mean I want anybody rounded up or punished or whatever: just that logic comes before politics.

as if identification by others should supersede self-identification. — Questioner

Identity is always socially negotiated. People aren't necessarily always what they say they are just because they say they are. Just because I say I'm an Olympic gold medalist or a world chess champion doesn't make it true.

The experiences of transgender persons tell us that the definition of “woman” or “man” cannot be based solely on the physical body at birth. — Questioner

Since they don't exist, this is not true.
