What is the theory of recollection and innate ideas?

Answer 1

This is derived from Socrates' belief that one's soul existed in past lives and knowledge is transferred from those lives to the current one. "These [ideas] were revealed in a former state of existence, and are recovered by reminiscence (anamnesis) or association from sensible things" [3]. The claim is that one does not need to know what knowledge is before gaining knowledge, but rather one has a wealth of knowledge before ever gaining any experience.

In Meno, Plato's character (and old teacher) Socrates is challenged by Meno with what has become known as the sophistic paradox, or the paradox of knowledge:

Meno: And how are you going to search for [the nature of virtue] when you don't know at all what it is, Socrates? Which of all the things you don't know will you set up as target for your search? And even if you actually come across it, how will you know that it is that thing which you don't know?[1]

In other words, if you don't know any of the attributes, properties, and/or other descriptive markers of any kind that help signify what something is (physical or otherwise), you won't recognize it, even if you actually come across it. And, as consequence, if the converse is true, and you do know the attributes, properties and/or other descriptive markers of this thing, then you shouldn't need to seek it out at all. The result of this line of thinking is that, in either instance, there is no point trying to gain that "something"; in the case of Plato's aforementioned work, there is no point in seeking knowledge.

Socrates' response is to develop his theory of anamnesis. He suggests that the soul is immortal, and repeatedly incarnated; knowledge is actually in the soul from eternity (86b), but each time the soul is incarnated its knowledge is forgotten in the shock of birth. What one perceives to be learning, then, is actually the recovery of what one has forgotten. (Once it has been brought back it is true belief, to be turned into genuine knowledge by understanding.) And thus Socrates (and Plato) sees himself, not as a teacher, but as a midwife, aiding with the birth of knowledge that was already there in the student.

The theory is illustrated by Socrates asking a slave boy questions about geometry. At first the boy gives the wrong answer; when this is pointed out to him, he is puzzled, but by asking questions Socrates is able to help him to reach the true answer. This is intended to show that, as the boy wasn't told the answer, he could only have reached the truth by recollecting what he had already known but forgotten.

Answer 2

The theory of recollection, proposed by Plato, suggests that we are born with knowledge that we "remember" from a previous existence in the realm of the Forms. This knowledge is accessed through learning and experience in our current lives. Innate ideas are those believed to be inherent in the mind at birth, such as basic mathematical principles or moral truths, as proposed by philosophers like Descartes and Leibniz.
