Study Notes

Meditation 1

Descartes begins by doubting everything in pursuit of a more solid foundation for knowledge.
His goal is to uncover true knowledge that is indubitable and can withstand rational scrutiny.
He uses a method of doubt to evaluate the truths he has accepted, questioning the reliability of the senses.

Project Initiation

The project is prompted by his reflection on the falsehoods he has believed throughout his life.

Method of Examination

Unable to review all opinions individually, Descartes targets the underlying principles that inform his beliefs.
The primary principle he challenges is reliance on sensory perceptions to verify truth.

Starting Point

Doubting the senses leads him to recognize that they can be deceptive, particularly regarding distant or small objects.

Method of Doubt

The method involves tracing knowledge back to a firm foundation of beliefs that are beyond doubt, aiming for certainty.

Three Senses Doubts

Perceptual Illusion: Acknowledges temporary sensory deception based on distance or size, yet affirms that sensory knowledge is generally reliable.
Vivid Dreaming: Challenges the distinction between dream sensations and waking experiences, emphasizing that sensory elements can arise from reality.
Deceiving God and Evil Genius: Hypothesizes an evil demon that actively deceives him, allowing for the possibility that all he thinks he knows could be false.

Impact of Dreaming and Evil Genius Doubts

These doubts highlight the unreliable nature of senses, as perceptions in dreams can mimic real-world experiences, with no clear markers to differentiate them.

Remaining Certainties

While sensory reliability is questioned, the existence of God and the foundational belief in the self remain intact.

Meditation 2

At the start of the second meditation, Descartes doubts the existence of everything, including senses and memory, questioning concepts like extension and movement.

Conclusion of Meditation 2

Realizes that the act of doubting implies the existence of a self that doubts.
Formulates the cogito argument: "I think, therefore I am," asserting that existence is guaranteed as long as he is the one contemplating doubts.
