👉 The evidence fluid, a term coined by philosopher Timothy Williamson, refers to the dynamic and context-sensitive nature of evidence in reasoning and argumentation. Unlike static or rigid forms of evidence, the evidence fluid acknowledges that the relevance, weight, and interpretation of evidence can change based on the context in which it is presented. This fluidity recognizes that what counts as evidence in one situation may not hold in another, and that the same piece of evidence can be more or less persuasive depending on the argument's framework. The concept emphasizes the importance of understanding evidence within its broader context, including the intentions of the arguer, the nature of the claim being made, and the overall discourse. This nuanced approach to evidence helps in constructing more robust and adaptable arguments, reflecting the complexities of real-world reasoning.
