A significant value of reading these books lies in the repeated realization that many traditional philosophical problems are actually vacuous. When people describe Wittgenstein's work not as typical philosophy but rather as a form of therapy, I now have a better understanding at another level. He doesn't offer many positive points directly but instead attempts to uproot our intuitions that certain positive points make sense. These books involve Wittgenstein applying his insight that semantic meaning is constituted by use (within a language game) to a series of examples. The application follows a rather formulaic pattern; by a third of the way into the book, one can predict how it will unfold for all the other examples. From my recollection, reading the Philosophical Investigations was much more exciting and enlightening; it had a greater variety of points and examples to present (though I could be mistaken as it's just from my memory). However, the repetition in the Blue and Brown books is very beneficial for receiving Wittgenstein's edification. His view is radically new and goes against all common philosophical intuition, so it requires a great deal of drilling to overcome these common intuitions. (After reading this, I'm aware that I'll need a lot more time to think about philosophical problems differently and truly internalize this message).
So Wittgenstein's overall points are as follows: (1) Philosophical problems are presented linguistically; they identify certain phenomena and pose questions about them. (2) Such identification of phenomena amounts to referring to or describing those phenomena using certain words, which are based on certain parts of speech. (3) Often, these parts of speech schematize our understanding of these phenomena in a way that gives rise to certain problems or paradoxes, or certain types of questions. (4) These questions turn out to be vacuous or meaningless once we realize that these parts of speech are based in certain language games; these parts of speech can only be accurately used under specific circumstances to deal with only certain phenomena, based on those games.
For instance, the mistake of transferring a schema from its original home or language game into a foreign, philosophical context occurs when philosophers ask "Does the future or the past exist?" This question presupposes that temporal tenses (future and past) are treated like physical objects, whose existence we can question. But this is inappropriate. Temporal tenses are nothing like physical objects in nature; objects that are subject to the question of existence necessarily exist over temporal durations. Time is not an object but a precondition for the experience of objects. This kind of mistake is similar to asking what the weather is like inside a thought or whether an emotion has passed its expiration date and is no longer "edible." In other words, Wittgenstein criticizes philosophers for constantly making category mistakes. The questions that can be coherently asked about a given phenomenon are determined by our ordinary language and common experience regarding that phenomenon. We ask about the weather when we are about to go outdoors; this question pertains to the outdoors, not to thoughts. Likewise, when we ask about whether something exists, this question pertains to objects, not to time.
Wittgenstein applies this insight about the context-relativity of meaning to a wide range of philosophical issues. Some highlights include questions about skepticism regarding other minds, what it means for something to possibly exist or that something can happen (modality or possibility), what it means to will for something to happen (volition or agency), and what it means to grasp a meaning or understand a rule (learning). In all cases, Wittgenstein's approach and conclusions are the same, and it is highly repetitive, but for the good reason of allowing the lesson to truly sink in.
I would recommend this to anyone who has read the Philosophical Investigations and wants to see the ideas introduced there played out in more concrete detail. Those ideas are indeed made clearer here. But they are not really expanded upon in any significant way; so if a reader feels that they've grasped the main ideas in that earlier work, I don't think there's a real need to read the Blue and Brown books.
A side note about some concerns I have: after reading this, I finally realized that Wittgenstein's account of semantic meaning is not unique to language at all. Any physical artifact, bodily gesture, or object or event that is embedded in a practical activity (based on forms of life) has "semantic meaning" by virtue of the same considerations Wittgenstein raises with respect to linguistic meaning. For example, in Wittgenstein's case of builders, the foreman says "Slab!" to a worker, and in the context of this language game, this expression has the semantic meaning of "Bring me a slab." But likewise, the slab itself has "semantic" meaning in that it is to be used in making the building, that it is to be passed to the foreman, etc. Everything that humans encounter (linguistic utterances or physical objects) within the context of a practical activity gains meaning that is determined by the conditions of that activity.
This is a concern because I had always assumed that Wittgenstein's insight was truly about language itself. His insight is rather about meaning more generally. The impression that it is about language is due to the fact that Wittgenstein's main purpose is to deflate philosophical problems, which are always presented linguistically. So all of his examples are about language. But the account he gives of linguistic meaning is inherently general or broad to such an extent that it does not pertain uniquely to language. The only reason this concern matters to me is that I'm interested in thinking about where linguistic meaning uniquely comes from, not just meaning generally. To address that question, Wittgenstein provides a starting platform but does not take you any further.
