| | Descriptive knowledge - Wikipedia, the free encyclopedia |
 | | Descriptive knowledge, also declarative knowledge or propositional knowledge, is the species of knowledge that is, by its very nature, expressed in declarative sentences or indicative propositions. |
 | | This distinguishes descriptive knowledge from what is commonly known as "know-how", or procedural knowledge, that is, the knowledge of how, and especially how best, to perform some task. |
 | | Knowledge can be classified into a priori knowledge, which is obtained without needing to observe the world, and a posteriori or empirical knowledge, which is only obtained after observing the world or interacting with it in some way. |
