Basic Sentences, Protocol Sentences
Sentences formulating the result of observations or perceptions or other experiences, furnishing the basis for empirical verification or confirmation (see Verification). Some philosophers take sentences concerning observable properties of physical things as basic sentences, others take sentences concerning sense-data or perceptions. The sentences of the latter kind are regarded by some philosophers as completely verifiable, while others believe that all factual sentences can be confirmed only to some degree. See Scientific Empiricism. — R.C.
