“They are both like and unlike” – reference to humans and animals.
The reading is discusses the profound differences between man and animals and how animals for example, possess human-like qualities in a certain aspect.
How this relates to media? I have no idea at all. But what I can make out from it is that unlike animals, man is able to create idea, therefore man is able to create. And through media, it is a form of self-creation/expression that animals are not able to comprehend. This is not to diminish the ability of animals. In fact, animals possess a quality that makes them different from us – it is their detachment with worldly stresses and issues that make them, well, animals. In a way lack of self-realisation can be burden-lifting and comfortable because they don’t have to experience an existential crisis that we humans do. Nonetheless, this inherent quality that we possess is what makes us essentially human – this is why we are able to create.
