As anyone who has played the Ultima series (from Ultima IV onward, anyway) knows, a fighter is all about Valor, but a paladin is all about Honor. 
Jokes aside, that to me is the essence of a paladin: he is a warrior of virtue. Unlike a fighter, he is not fighting for a good cause simply because he is paid, or because he is going along with a friend. He is deliberately and consciously choosing to do so: defending the innocent, protecting the weak, helping the helpless, bringing justice to the wicked, etc. As a class, paladins should also be more discerning than clerics: you wouldn't find a paladin serving a god of darkness or greed, for example.
In 3e and ealier editions, this was done by restricting paladins to mostly the Lawful Good alignment. Early 4e opened up the paladin class to every alignment (personal view: ugh
), but Essentials brought back some of that flavor by tying paladins to a virtue (specifically, valor and sacrifice).
In 5e, I hope I get my warriors of virtue back. Mind you, if I were to start from a clean slate, I probably wouldn't have a separate paladin class. I'd start with a basic fighter and offer the paladin abilities through a series of divine boons which the character must earn. Wouldn't that be an interesting solo adventure path?
