Can ideas be said to exist in the same way as other forms of existence?
Certainly they, like other objects, materials, or processes can be seen to exist throughout their interactions within their environments. Also, like other objects, materials or processes (that is, those things external to a person's imagination, those that occupy three dimensional space or exhibit mass) ideas can be seen from a multitude or even perhaps an infinity of vantage points. They also often have structures similar to the body in which they reside (the mind, the perceptually fueled imagination world of consciousness, or unconsciousness to the extent this could be said to exist). They may even control complex structural processes, generating or moving masses of other forms while having no measurable weight or even a discernible physical body and that is very interesting, isn't it?
Nonetheless, ideas must be considered special sorts of forms, even when they can be seen to exist in many people's imaginations or consciousnesses simultaneously, even when they drive the creation of three dimensional forms exhibiting mass. The can be said to exist, but they are "special," aren't they?
