It means to have ideas before we born.

Are we born with knowledge?The assumption is that we born as a

‘blank slot’ but Plato believe that the human soul exists

eternally,and exists in a world of form(or idea)before life.

B.ReasonIs the main source of knowledge and 5 senses only give you opinion,not reason.e.g.Descartes’ wax argument.

He states’’ we come to know them by the power of our own native intelligence,without any sensory experience.

Wax has certain characteristic,it may burn and turn black,However,it

is still wax .He concludes that these

characteristic are not inherent to the wax itself

Prove something with certainty

rather than reason.e.g

existance of God(Descartes’)
