Descartes’ Third Meditation

  • His aim is to offer an argument for the

existence of God, based simply on what (after

the first two Meditations ) he knows with

certainty.

  • He begins by reviewing:
    • His doubts, and
    • What he now knows, and
    • What he need not doubt.

Med 3: Paragraph 1

I will now shut my eyes, block my ears, cut off all my senses. I will regard all my mental images of bodily things as empty, false and worthless .... I will ... examine myself more deeply, and try ... to know myself more intimately. I am a thing that thinks, i.e that doubts, affirms, denies, ... [etc]. This thing also ... has sensory perceptions; ... even if the objects of my sensory experience ... don’t exist outside me, still sensory perception ..., considered simply as mental events, certainly do occur in me.

Med. 3, Paragraph 3

I previously accepted as perfectly certain and evident many things ...—the earth, sky, stars, and everything else that I took in through the senses—but in those cases what I perceived clearly were merely the ideas or thoughts of those things that came into my mind .... But I used also to believe that my ideas came from things outside that resembled them in all respects. .... [This] was false; or anyway if it was true it was not thanks to the strength of my perceptions.

Med. 3, Paragraph 6

When ideas are considered solely in themselves and not taken to be connected to anything else, they can’t be false; for whether it is a goat that I am imagining or a chimera, either way it is true that I do imagine it. .... All that is left—the only kind of thought where I must watch out for mistakes—are judgments. And the mistake they most commonly involve is to judge that my ideas resemble things outside me.

What do I know?

  • I know that I exist.
    • I know that I am a “thinking thing,” a “mind.”
      • i.e., the subject of conscious experiences.
        • Med. 2 and 6 argue that this “mind” is non-material.
  • I know I have ideas or sensations “in” my mind.
    • These “mental contents” are what I “directly” or “immediately” perceive.
  • I “judge” (i.e., infer ) that these mental contents are

caused by things that exist outside my mind, and that my ideas “resemble them.”

  • This is what Med. 4-6 attempt to prove.

Descartes, Locke, Berkeley

  • All three accept (without much argument) that what we directly or immediately know are only “ideas” or other “mental contents.”
  • Descartes argues (in Med. 3-6) that there is a world outside our mind.
  • Locke accepts (without argument) that there is such a world, but claims that our sensations do not always resemble it.
  • Berkeley argues that there is no world outside mind (yours, mine, and God’s).

Terminology

  • Empiricism:
    • All knowledge ultimately rests upon sense experience.
    • Our justification for claiming we know something must always end up with something we perceive with our senses. - Seeing is believing. - Rationalism: - Not all knowledge ultimately rests upon sense experience. - At least some (maybe all!) knowledge can be justified without appealing to sense perception. - E.g., 2+2=4.
