The Wax Argument

He used the Wax Argument to prove that Rationalism is more reliable and the most secure source of knowledge.

Premise 1: Observing a piece of wax using senses will reveal the properties it possessed like shape, color, and scent.

Premise 2: When the piece of wax is melted, these properties change completely.

Premise 3: But we still recognize the melted wax as the same substance.

Premise 4: I cannot know this through my senses, which only provide access to sensible properties.

Conclusion: My understanding (Thinking) is more reliable than my senses.
