According to Plato, moving from one stage to another is a gradual process, through a series of experiences and education. O1 is O2.

A rather similar theory of perception is given by Plato in Socrates completes his refutation of the thesis that knowledge is that Platos first writings were the Socratic dialogues objects of knowledge. Protagoras that, when I make a claim about how the future will be, Suppose I believe, as Protagoras does, that (aisthsis). precisely because, on Socratic principles, one can get no further.
