* Fluency is a skill, not a reflection of thought: Fluency in a language primarily means being able to communicate effectively in that language. It involves speaking, reading, writing, and understanding, but it doesn't inherently indicate the depth or complexity of someone's thoughts.
* Thought is internal: Thinking is a complex process that happens in the mind. We can observe language and communication, but we cannot directly observe someone's internal thoughts.
* Thinking involves more than language: While language is a powerful tool for expressing thoughts, it's not the only way we think. We can think in images, emotions, and abstract concepts that may not be easily translated into words.
* Fluency can be learned without deep understanding: It's possible to learn a language by memorizing phrases and grammar rules, but that doesn't necessarily mean understanding the underlying concepts, implications, or nuances.
* People can be fluent but lack critical thinking skills: Fluency is about using language, but it doesn't guarantee critical thinking, problem-solving, or intellectual curiosity.
In short, fluency in English is a communication skill, and while it can be a tool for expressing thoughts, it's not a direct measure of a person's thinking process.
