As far as I know about solipsism is that the solipsist I guess would be me, and I am the only mind that exists and everything I perceive from my senses and the experience of the world is solely a product of my mind.
The subject is me, and the object I perceive,'The World' is a product of that subject.
Is solipsism therefore a declaration of the 'individual' to themselves, that there is no subject and no object because you cannot differentiate between the two?
What then would that 'individual' declare their experience to be if there is no subject or object?
