Descartes' Meditations: Epistemology, Method, and Philosophy

What was Descartes' primary dissatisfaction with his 17th-century education?

He found contemporarily accepted scientific and philosophical doctrines to be broadly unjustified and unstable.

In the context of the Meditations, what mathematical method does Descartes' initial philosophical approach resemble?

Indirect proof (reductio ad absurdum).

Descartes' Meditations was written in opposition to which then-popular scientific framework?

Aristotelian hylomorphic science.

What is the stated goal of the meditator's 'blank slate' approach?

To create an ideal, non-illusory, evidence-based scientific conception of the world.

According to Descartes, why should we reject 'the opinions and surmises of others' in the pursuit of truth?

One must personally examine premises and evidence to reach independently justified conclusions.

Why is the first-person perspective considered indispensable to the Meditations?

It encourages the reader to personally undertake the chronological thought experiments to reach the same conclusions.

In 'Discourse on Method', Descartes argues that understanding the nature of a complex whole requires _____.

Abstracting away from the whole to study the simplest constituent parts (reductionism).

What is the ultimate 'foundational and lasting' goal of the Meditations beyond specific scientific facts?

Establishing a justified scientific method.

The chronological introduction of radical sceptical arguments in Meditation 1 is known as the _____.

Method of doubt.

Why does the meditator initially doubt the reliability of the senses?

Because the senses sometimes deceive us through simple illusions.

What argument does Descartes use to doubt immediate, salient sensory facts, such as 'I am sat by the fire'?

The Dream Argument.

In Meditation 1, what kind of truths initially seem to survive the Dream Argument?

Simple analytic truths or tautologies (e.g., $2 + 2 = 4$).

How does the meditator use the concept of an omnipotent God to doubt mathematical truths?

An omnipotent God could induce a false belief that $2 + 2 = 4$ when it is actually not.

If one rejects God for a naturalistic origin, why does the problem of deception deepen for the meditator?

An imperfect origin provides no guarantee that human faculties are oriented towards truth.

What is the primary function of the 'Malignant Demon' in Meditation 1?

A psychological tool to prevent the meditator from lazily slipping back into old, uncertain beliefs.

Define the 'withholding policy' established at the end of Meditation 1.

Treating any belief that is not certain and indubitable as if it were false.

What is 'belief chunking' in the context of Cartesian doubt?

Examining the epistemic groundings of types of beliefs rather than analysing every individual opinion.

Which philosopher raised the concern that Descartes' radical doubt could lead to atheism and the subversion of laws?

Antoine Arnauld.

What was Pierre Gassendi's methodological objection to the 'Malignant Demon' scenario?

He viewed it as dramatic sophistry, arguing that acknowledging human weakness is sufficient for doubt.

What modern epistemological concern exists regarding Descartes' 'feigning' of disbelief?

Whether belief is truly a voluntary process that can be turned off at will.

Term: Archimedean Point

A hypothetical fixed starting point from which one can objectively analyse a subject.

Why is the fact that the meditator is being deceived considered proof of existence?

A demon cannot deceive something that does not exist.

Which proposition is described as 'necessarily true, whenever it is conceived by the mind'?

I am, I exist (the Cogito).

If the Cogito is viewed as a formal argument, what is its logical symbolisation?

$P \therefore Q$

Why does Descartes reject the Cogito as a standard syllogistic deduction?

Logical inferences could be erroneous under hyperbolic doubt, so it must be a unitary intuition.

In Meditation 2, after stripping away physical concepts, what does the meditator conclude he is in the 'strictest sense'?

A thinking thing (mind, intellect, or reason).

What is the primary purpose of the 'Wax Argument' in Meditation 2?

To prove the mind is better known than the physical body.

According to the Wax Argument, how is the true essence of physical bodies grasped?

Through pure mental scrutiny (intellect) rather than sense experience or imagination.

Concept: 'Seeing1' (Wilson)

A state of pure subjective awareness that the Demon cannot deceive (e.g., dreaming of a tree).

Concept: 'Seeing2' (Wilson)

A way of acquiring knowledge about the actual external world, which is subject to doubt.

Principle: Intellect Priority

The hidden nature of physical bodies is perceived by the intellect, not sensory experience.

Principle: Mind Priority

Knowledge of the mind is easier to acquire and more deeply understood than knowledge of the corporeal world.

What was Thomas Hobbes' objection to the nature of the 'I' in Meditation 2?

The subject doing the thinking must be corporeal (a result of motions in a physical body).

How does Descartes respond to the idea that thought is a faculty of the brain?

He asserts that acts of thought have absolutely nothing in common with physical acts.

In Meditation 3, what general rule does the meditator derive from the certainty of the Cogito?

Whatever is perceived very clearly and distinctly is true.

Identify the three categories of thoughts classified in Meditation 3.

Ideas (pictures of things), volitions, and judgements.

Why are 'ideas' and 'volitions' not inherently open to error?

They are simple experiences; error only occurs when a 'judgement' is made about their relation to reality.

Term: Adventitious Ideas

Ideas that are perceived as coming from the outside world.

Term: Innate Ideas

Ideas derived from one's own nature.

Term: Invented Ideas

Ideas created by the meditator himself.

What is 'objective reality' in the context of Cartesian ideas?

The representational content or the 'perfection' of the thing represented by an idea.

Principle: Causal Non-Inferiority

A cause must contain at least as much reality as its effect.

In Meditation 3, why can't the meditator be the source of his own idea of God?

The meditator is a finite substance, but the idea is of an infinite substance, which requires an infinite cause.

Descartes argues that the idea of God is innate, placed within him like the _____.

Mark of the craftsman on his work.

How does the meditator argue for God's existence based on the 'preservation' of life?

The power to sustain a lifespan across unconnected moments is the same as the power to create.

Why does the meditator conclude that God cannot be a deceiver?

Because God possesses all perfections, and deception relies on a 'defect'.

What is the 'Cartesian Circle' as raised by Arnauld?

Proving God's existence via clear and distinct perceptions, while relying on God to guarantee those perceptions.

In response to the Cartesian Circle, what distinction does Descartes make regarding 'attention'?

He is certain of axioms while paying attention to them; God is needed to guarantee memories of past perceptions.

What is the 'psychological validity' defence of the Cartesian Circle?

The meditator is only in the business of personal conviction rather than normative logical justification.

Gassendi argued that the mind might be a _____ that permeates the body, rather than a separate substance.

Thin vapour or 'flower of matter'.

Why does the meditator conclude that the wax remains the same even after melting?

Because the mind perceives the wax as an extended, flexible, and changeable thing through the intellect.

According to the source material, what is the 'Authority Principle'?

An inadequate everyday sorting-procedure for truth based on accepting tradition or experts.

What is the 'Conformity Policy' mentioned in the background to the meditations?

An everyday procedure of accepting beliefs because others do so, which Descartes rejects for science.

What modern objection exists regarding the 'Dream Argument'?

Whether it is possible for a 'dream self' to believe something while the 'conscious self' is asleep.

The meditator views the Cogito not as a deduction, but as a singular, unitary _____.

Intuition.

What is the 'hierarchy of ideas' mentioned by Wilson in Meditation 3?

The metaphysical assumption that ideas of infinite substances rank above ideas of finite substances.

According to Descartes, why is an omnipotent God more 'troubling' than a malevolent demon regarding math?

God has the power to make $2 + 2 = 5$ seem true, even if it is not.

In Meditation 1, why does Descartes assume a demon exists even if he doesn't 'believe' in one?

To bolsters the problem of doubt and reach the strongest possible sceptical thesis.

Descartes claims that to understand the nature of something, we must study its _____.

Simplest constituent parts.

Why does the meditator reject the idea that he could have created himself?

If he were his own creator, he would have given himself all the perfections he has an idea of.

According to the source, why might the meditator's epistemic state be worse if the psychological validity defence is true?

He was already convinced of many things before he began doubting, making the process redundant.
