Document Summary
You know what a dog is, but what knowledge is knowing what a dog. 303) is: know because of a dictionary definition (has hair/4 legs/bars/wags tail) Use it as a checklist when trying to define something but it resembles features of other animals too. Argued that simple terms we use everyday don"t actually. We come up with these definitions for the concepts (dog may not always have 4 legs so is it really a dog?) and its easy to find expectations for them. Wittgenstein came up with: family resemblance: features that are similar but not generalized to every concept of something. E. g. , family not every family looks the same but within each subgroup each family shares attributes that resembles them to be from the same family extent. There is no ideal but families must resemble someone who looks like the ideal and taking some of their features through their genes etc. This is how we recognize families/people looking similar.
