Descartes’ Provisional Morality and Methodic Doubt

PART 3: A MORAL NEED NOT REMAIN PROVISIONAL

Irresolute in Action

2. Maximum of Moral Provisional

First Maxim

  • Obey the laws and customs of the country you live in.
  • Follow the more moderate opinions of others.
  • Be modeled after sensible men.
  • Pay more attention to what they do than what they say because not everyone says what they think.
  • Consider extreme opinions that dispose of the highest freedom.

Constancy in Action

Second Maxim

  • Be firm and resolute in action.
  • Analogy: a man lost in the forest is still strong.
  • To get anywhere in life, it is usually not prudent to delay the release of remorseful actions.

Third Maxim

  • Winning over oneself rather than fortune.
  • Only our own thoughts are in our power.
  • Limit our desires to what is possible according to our nature.
  • Make a virtue of necessity.

Employ Fourth Maxim in the Cultivation of Reason

  • The acquisition of truths is a source of satisfaction.
  • Reason is the foundation of the three previous points.
  • The will is determined by sufficient understanding to act correctly and judge well.

After discarding these reflections, apply them to remove your old opinions.

  • Comments on nine years of travel experience, etc.
  • Your question is not of skeptics.
  • Nine years elapse without taking sides on philosophical questions.
  • Decision to retire to a quiet place to develop his philosophy (Holland).

PART 4: Methodic Doubt

Reject Everything You Doubt to See if Anything Remains Certain

  • Doubt the information from the senses.
  • The senses sometimes deceive us.
  • Argument: How do we know we are not dreaming when we sleep?
  • Geometric doubt shows men are wrong to argue.

First Truth

  • “If I doubt, I think; therefore, I am.” This is the beginning of philosophy.
  • What am I?
  • I am a soul, a thinking substance, distinct from the body and easier to know.

The Criterion of Truth

Everything conceived clearly and distinctly is true.

Nature of God and Proofs

  • First Proof: The idea of perfection that is in me can only have been produced by a perfect being.
  • Second Proof: If I had produced the perfections I possess, I would also have given myself those I do not possess, and whose ideas are in me.
  • Third Proof: Existence is a perfection.
  • Many find it hard to know God because they do not rise above the senses, and the ideas of God and the soul are not given by the senses.
  • But we must distinguish the sensible and the intelligible. God is imaginable.

God as the Guarantee of Truth

  • Corporeal things are less certain than God and the soul.
  • To give moral certainty (less reality to the waking dream), one must assume the existence of God.
  • God’s own criterion of certainty is guaranteed because God is perfect.
  • All our true ideas come from God; false ideas are due to our imperfection.
  • God is the warranty of mathematical truths, which are true even if we are dreaming.
  • There is no doubt about the evidence of reason, even if the imagination and the senses contradict it.
