Solipsism is a epistemological concept, according to which the self alone is real to consciousness, all other contents of consciousness are mere ideas (subjectivism), as methodological rule used e.g. by Descartes. The main claim of solipsism is that all that exists is only a projection of one’s individual perceptions, all the while, the reality is just a collection of its subjective impressions: all objects, people, things, shapes etc. experienced, are merely the creation of mind.
Solipsism is extreme subjective idealism in the epistemological sense. Solipsist not only denies the existence of the material world. The most controversial argument made by the solipsism is a denial of the existence of consciousness in other people and other people in general.
Solipsist argues that contact with the world is always a personal experience. After all, other people’s experiences are always secondary, and may be perceived only by analogy to one’s own experiences. cf. 2
