Desires are fundamentally different from needs

It’s true that when people strongly desire something, such as a new shirt, they might feel like they ‘need’ it – but they don’t need it in the same way that they need water or food. Their survival isn’t at stake.

Desire (as opposed to need) is an intellectual appetite for things that you perceive to be good, but that you have no physical, instinctual basis for wanting – and that’s true whether those things are actually good or not.
