Descartes' Meditation Two: The Nature of the Human Spirit

Meditation Two: The Nature of the Human Spirit

The Certainty of Existence

After establishing the truth of "I think, therefore I am," Descartes identifies an evil spirit as the third cause of doubt, alongside the fallacies of the senses and the inability to distinguish waking life from sleep. This powerful, intelligent being strives to deceive him. However, Descartes concludes that even if he is being deceived, he must exist as a thinking being to be subject to such deception.

The Distinction Between Body and Soul

Descartes re-evaluates his previous understanding of the self, specifically the distinction between the body and the soul:

• The Body: Associated with sensory limitations and negative connotations, similar to Plato's view of the body as a prison for the soul.
• The Soul: Descartes doubts the existence of the body but cannot doubt the existence of the soul, as thought is an inseparable attribute of his being.

He reaffirms: "I think, therefore I am." If he were to cease thinking, he would cease to exist; therefore, he is fundamentally a thinking thing.

The Wax Argument and Sensory Perception

Descartes addresses the paradox that sensory perceptions often feel more real than internal thoughts. He uses the example of a piece of wax:

• When placed near a fire, the wax melts and its physical properties change entirely.
• Despite these changes, the wax remains the same object.
• The essence of the wax is not found in its sensory qualities, which are flexible and changing, but through an inspection of the spirit.

Conclusion: The Primacy of the Mind

Descartes argues that physical bodies are understood through the intellect rather than the senses. We perceive objects more clearly through thought than through touch or sight. Consequently, he concludes that nothing is easier to know than the human spirit, as it is the primary instrument through which we conceive of all reality.
