DESCARTES
THE RATIONALIST
What can we Know?
INNATE IDEAS
Descartes' rationalism sees knowledge as accessible only by reason and not by the senses, which can not be trusted. Moreover, true knowledge is innate, that is inborn, in all human beings. Innate ideas, such as the equality of the three angles of a triangle to two right angles, are absolute truths waiting to become clear and evident through reasoning. They are immutable and eternal because they are part of the pattern of God's creation. For God has established his laws in nature and imprinted them on our minds so "there is no single one we cannot understand if our mind proceeds to consider it."
