So an idea is said not to exist unless it is in the outer world as opposed to in our skulls. Once an idea is out there it is real and can be accepted, rejected, discussed and so on. So if we are not egotists we believe that our thoughts are within, subjective, and our ideas are not true ideas until they have evacuated our minds like so much cognitive sewage. This means we must push forth our internal ideas, Invie, to solidify it, which is what we are doing with social media, we are exposing ourselves, we are releasing ideas to validate our existence. By positing something we say this is me, this is what I feel, believe, what I own mentally. We are constantly verifying and externalizing our selves to confirm our selves, creating our presence in the wide world.
