What philosophical view holds that only one's own mind is certain to exist?
Show answer
Solipsism
Solipsism comes from the Latin words 'solus' (alone) and 'ipse' (self), reflecting the idea that the individual mind is the only reality that can be known. While it is an extreme form of skepticism, it highlights the philosophical challenge of proving the existence of an external world or other minds. For a true solipsist, the entire universe is essentially a private dream where nothing else truly exists.
