what is sydney shoemaker's argument against functionalism in his "The Inverted Spectrum" paper? is he for or against it? is he on the fence about functionalism?

[gritty lagoon]

In Sydney Shoemaker's paper "The Inverted Spectrum," he presents a thought experiment that challenges functionalism, a popular theory of mind which suggests that mental states are constituted by their functional roles, rather than by the specific material or biological components that constitute them.

The Inverted Spectrum thought experiment posits that if two people's color experiences were inverted relative to one another—so that one person sees red when the other sees green, and so on—but their behavioral reactions to colors remain the same, it would still be possible for their mental states to be functionally identical. This is because, despite their opposing experiences, the two people would react to stimuli in the same way, with no detectable difference in behavior.

Shoemaker uses this thought experiment to argue against functionalism, claiming that the possibility of the Inverted Spectrum reveals that mental states cannot be solely determined by their functional roles. On the basis of this argument, it can be concluded that Shoemaker is against functionalism.

However, it is worth noting that his argument does not definitively prove the position incorrect; rather, it raises doubts about the completeness of functionalism as a theory of mind. For this reason, some people may still engage with functionalism in a critical way, recognizing that while it has some merit, there may be aspects of the theory that need further exploration or revision.

explain the "boy girl paradox" or "Two boys problem" in laymans terms. it seems so counterintuitive.

[gritty lagoon]

The "Boy Girl Paradox" or "Two Boys Problem" is a probability puzzle that challenges our intuitions about how to calculate probabilities. Here's the problem, simplified:

A family has two children. Given that one of the children is a boy, what is the probability that the other child is also a boy?

At first glance, it might seem like the probability should be 1/2 or 50%, simply because there are only two possibilities for the other child: either it's a boy, or it's a girl. However, this answer is misleading because we're not accounting for all the possible scenarios.

To understand why the correct probability is actually 1/3 or approximately 33.33%, let's break down the possible scenarios for a family with two children:

1. Boy, Boy (BB)
2. Boy, Girl (BG)
3. Girl, Boy (GB)
4. Girl, Girl (GG)

Now, we already know from the problem that at least one of the children is a boy. That means we can eliminate the last scenario (GG) from consideration. This leaves us with three possible scenarios:

1. Boy, Boy (BB)
2. Boy, Girl (BG)
3. Girl, Boy (GB)

Notice that there are 2 cases in which one child is a boy and the other is a girl (BG and GB), and only 1 case in which both children are boys (BB). Therefore, the probability of having two boys, given that at least one child is a boy, is 1/3 or approximately 33.33%.

The key to understanding the seeming counterintuitiveness of the Boy Girl Paradox is recognizing how the initial information—that we know one of the children is a boy—impacts our calculations of the possible scenarios.

aren't BG and GB essentially the same result in real life? saying that it's a 1/3 chance feels like a purely hypothetical division
