Emotions are complex subjective cognitive states that govern human behaviour and interactions. In the early stages of our evolution, before we had the vocabulary and apparatus for thought, emotions were all we had – which is why they still feel so raw and hard to process, because they predate thought. Emotions, in a sense, are just thoughts of a different kind. Think of them as proto-thoughts lent corporeality by your body. This becomes clearer when we look at how emotions actually function.
