Sense data
（重定向自Sensibilia）
In the philosophy of pe****tion, the theory of sense data was a popular view held in the early 20th century by philosophers such as Bertrand Russell, C. D. Broad, H. H. Price, A.J. Ayer, and G.E. Moore. Sense data are supposedly mind-dependent objects whose existence and properties are known directly to us in pe****tion. They are supposed to be unanalyzed experiences inside the mind, which appear to subsequent more advanced mental operations exactly as they are.
