Realism: Naïve Realism

**Naïve Realism** (or Direct Realism) is the common-sense view that **physical objects exist independently of human minds** and that we perceive them **directly** and exactly as they are.

• **Principle:** What you see is what you get. The object's properties (color, shape, taste) are inherent in the object itself.
• **Criticism:** Easily refuted by sensory illusions (e.g., a stick looking bent in water, or color changing under different lights).

Realism: Representationalism

**Representationalism** (or Indirect Realism) holds that we do not perceive external objects directly, but rather perceive **mental representations (ideas or sense data)** of those objects.

• **Mechanism:** The external object causes an impression (representation) in the mind.
• **Locke's Distinction:** This theory relies on the distinction between:
  • **Primary Qualities:** Properties inherent in the object and inseparable from it (e.g., shape, size, motion). These are accurately represented.
  • **Secondary Qualities:** Properties that are *in the observer* and are powers of the object to produce sensations (e.g., color, taste, sound). These are *not* accurately represented.
• **Criticism:** Leads to **Skepticism** because if we only know our *idea* of an object, we can never prove the external object exists or accurately resembles the idea.

Realism: Neo-Critical Realism

**Neo-Critical Realism** is an attempt to overcome the limitations of Representationalism without resorting to Naïve Realism. It accepts that knowledge involves mental interpretation (Critical) but maintains that the object of knowledge is genuinely external and independent (Realism).

• **Core Idea:** The act of perception is not a simple reception of data, but a complex, interpretive act. However, the external object itself is a reality that exists independently of the act of knowing.
• **Relation:** They hold that the mind apprehends the object through its essences or characters, not just through raw sense data.

Idealism: Subjective Idealism of Berkeley

**Idealism** holds that ultimate reality is fundamentally **mind-like** (consciousness, spirit, or idea). **Subjective Idealism** (George Berkeley) takes this to the extreme, asserting that physical objects do not exist independently of being perceived.

Formula: ***Esse est percipi*** (To be is to be perceived). Nothing exists except minds (spirits) and their ideas.

• **Refutation of Matter:** Berkeley argued Locke’s notion of *Substance* or *Matter* that underlies primary qualities is incoherent, unperceived, and therefore meaningless.
• **The Role of God:** To explain why the world doesn't vanish when no human is looking, Berkeley claims that the world is sustained by being perpetually perceived by the infinite mind of **God**.

Idealism: Objective Idealism of Hegel

**Objective Idealism** (G.W.F. Hegel) maintains that reality is ultimately **Mind** or **Spirit** (*Geist*), but this Mind is a universal, objective, rational structure independent of any single, particular consciousness.

• **The Absolute:** Reality is a single, evolving, rational system called the **Absolute Spirit** or **Absolute Idea**.
• **Process:** The Absolute unfolds itself through a logical, historical process known as the **Dialectic** (Thesis, Antithesis, Synthesis).
• **Contrast with Berkeley:** Berkeley’s idealism is psychological and individual; Hegel’s idealism is logical, historical, and universal. The world is not my idea; it is the unfolding of the Absolute's Idea.
