In this paper, I consider a number of philosophical critiques of language and describe how their criticisms compare. In particular, I discuss how the current trend in the philosophy of language known as conceptual engineering fits into this tradition and to what extent it can be considered a critique of language per se, rather than a method of addressing dissatisfactions with certain individual terms. I suggest that criticisms can be divided allegations of two types of shortcoming: dangers and deficiencies. In (...) the category of dangers, I consider some well-known examples from the history of philosophy, and suggest that they partly rely on an unexpressed from of Linguistic Determinism. I then move on to the deficiencies highlighted in the critiques offered by Wittgenstein in the Tractatus Logico-Philosophicus, and Mauthner in his Contributions to a Critique of Language. These form a pair of apparently opposite ways of considering the flaws in language, but I shall argue that they have much in common. I then describe the conceptual engineering movement and its mission to provide ‘improved’ meanings of certain terms. I show that implicit in the assumptions behind conceptual engineering are criticisms of language of both varieties – current meanings are seen as dangerous as they represent a threat to social justice, and the system of allocation of meaning is seen as flawed and in need of external intervention.

In his 1955 essay "Meaning and synonymy in natural languages", Rudolf Carnap presents a thought experiment wherein an investigator provides a hypothetical robot with a definition of a concept together with a description of an individual, and then asks the robot if the individual is in the extension of the concept. In this work, we show how to realize Carnap's Robot through knowledge probing of an large language model (LLM), and argue that this provides a useful cognitive tool for conceptual (...) engineers to compare the extension of a proposed concept definition to the extensional knowledge represented as facts in a given knowledge base, providing a possible solution to the implementation problem in conceptual engineering.
