What does he that falls in love with himself has no rivals mean?

Answer 1

Oh, dude, that's like saying if you're so into yourself, you won't see anyone else as competition because you're too busy admiring your own reflection. It's basically a fancy way of saying Narcissism makes you blind to other people's awesomeness. So, like, maybe take a break from staring at yourself in the mirror and notice the cool folks around you, you know?

Answer 2

This phrase means that someone who is overly self-absorbed or narcissistic has no competitors or challengers because they are solely focused on themselves. When a person is in love with themselves, they are not interested in forming meaningful connections or relationships with others, as they believe they are superior to everyone else. This can lead to isolation and a lack of genuine interactions with others due to their self-centered mindset.

Answer 3

A possible meaning is that one who falls in love with himself will not find many other people interested in loving him; he won't be very attractive to others. As a result he will have only himself as a suitor. Similarly but from a slightly different perspective, a person in love with himself may know other people who want to love him, but his own affection for himself will be more important to him than their desires to love him.

This is applicable equally to men and to women. It is written with masculine pronouns following an older and now mostly outdated convention that masculine pronouns are used when the reference is to people in general.
