Hot dogs and knowledge

A quick analogy occurred to me concerning the different between Ilm and Irfán, that is, between acquired knowledge and the deep understanding of a thing.

The former is reading that animals are treated poorly, and that hot dogs are made of terrible things, yet it doesn’t stop you from enjoying them. The latter is visiting the factory, and then the treatment plants, and having your appetite forever removed by that knowledge, by an awareness you can’t unknow.
