Impressions and Ideas: Foundations of Knowledge
David Hume distinguished between impressions (vivid sense experiences) and ideas (fainter mental representations derived from impressions).
Hume’s Two Types of Knowledge

The Problem of the Evil Genius
Part of the nature of the human spirit is to question the body’s reality. Considering all doubts, false perceptions, and opinions, one might conclude that we have no senses and no kind of reality. In his Meditations, Descartes repeats this deduction to resolve some emerging contradictions.
This apparent contradiction arises in the concept of the evil genius: if God is infinitely good and infinitely powerful, it seems impossible

Fundamental Principles of Logic
Modus Ponens (MP)
Given a conditional statement and its antecedent as premises, we can derive its consequent as a conclusion.
Implication Introduction (II)

Conjunction Introduction (CI)
If we have two premises, we can conclude their conjunction.
Conjunction Elimination (CE)
Given a conjunction as a premise, we can conclude any of its individual members.

This theory sought to provide an intermediate response to the pre-Socratic debate. Plato posited the existence of two distinct realms: the Ideal World (or World of Forms) and the Sensible World.
The Ideal World, accessible through reason, is characterized by timeless, unique, continuous,

Understanding Idealism and Dualism
Types of Philosophical Approaches
- Idealism: The idea ‘actually means what X idea?’

Kant’s Transcendental Idealism
Ideas are the universal form of human thought that gives the information it receives through the senses. The qualities of objects change depending on how they are perceived. Objects have a primary existence (duration), each
