Solipsism

[Mark Zuckerberg]

The belief that the person holding the belief is the only real thing in the universe. All other persons and things are merely ornaments or impediments to his happiness.

[Tanya Shivari]

Philosophical theory which holds that everything is a product of my mind. Given a mention in George Orwells 1984, lending it greater recognition than it otherwise would have enjoyed. Now used as a synonym for self-absorption.

[Tanya Shivari]

Solipsism is the notion that the only thing that can be experienced and proven rationally, is the first person experience. As you read this you view it from the filter of idiocy that you normally see everything from, e.g. the first person. It is impossible to refute, and it doesnt mean that a person is narcissistic if they believe in it. Nor does it mean that the person believes they are the only thing that exists, it means that they can rationally believe in only themselves as everything else is beyond their experience, much as i cannot rationally believe in Peru until i visit it, but were not all perfect.

[Jessica]

The philosophical theory that one is the only person that actually exists, and everything else is constructed as a result of their imagination, including everybody they know and everything thats ever happened. In other words, its an excuse to be a complete arsehole.

This is not slang.
It means a perspective based on ones
own individual situation
rather than a multiperson perspective.
