Descartes

Descartes wanted to seek out how someone acquires knowledge rather than knowledge in itself. If we were to sit back for a second and think about how did we learn about something, like space is made up of plants and stars. It isn't something that is just known, it must require some type of research and requires someone to become knowledgeable about it, but how could someone acquire knowledge that no one else knows about. Descartes thinking at times makes a lot of sense, while we go about life just assuming what we are taught is correct should we not stop for a moment and wonder how did that person acquire the knowledge that they have passed onto us....
