Block VI: Idealism – Subjective and Objective

1. Chapter Summary (Quick Revision Note)

1. What is Idealism?
In epistemology, Idealism is the theory which holds that the object of knowledge is dependent on the mind of the knower. According to Idealism, mind or spirit is the ultimate reality. The external physical world has no independent existence apart from the mind that perceives it.

2. Types of Idealism:
Idealism is primarily divided into two types:

• Subjective Idealism (Advocated by George Berkeley)
• Objective Idealism (Advocated by G.W.F. Hegel)

3. Subjective Idealism (George Berkeley):

• Core Concept: Berkeley’s philosophy is summed up in his famous Latin phrase “Esse est percipi”, which means “To be is to be perceived” (অস্তিত্ব প্ৰত্যক্ষ নিৰ্ভৰ).
• Rejection of Matter: Berkeley completely rejects John Locke’s concept of an independent material world. He argues that what we call “objects” (like an apple or a table) are nothing but collections of ideas or sensations in our minds.
• Primary and Secondary Qualities: Berkeley rejects Locke’s distinction between primary and secondary qualities. He argues that primary qualities (size, shape) are just as subjective and mind-dependent as secondary qualities (color, taste).
• The Role of God: A major criticism of Subjective Idealism is Solipsism (the belief that only my mind exists). If a tree only exists when I look at it, does it disappear when I close my eyes? To solve this, Berkeley introduces the Infinite Mind (God). Objects continue to exist even when no human is looking at them because they are permanently perceived by the mind of God.

4. Objective Idealism (G.W.F. Hegel):

• Core Concept: Hegel’s philosophy is summarized in his statement: “What is rational is actual and what is actual is rational.” He believed that Thought and Reality are at bottom identical.
• The Absolute Idea: According to Hegel, the ultimate reality is not the individual human mind, but the Absolute Mind, Absolute Spirit, or Absolute Idea.
• The World as Manifestation: The external physical world is not an illusion or just a personal idea. It is a real, objective manifestation (expression) of the Absolute Mind.
• Reconciliation: Hegel’s Objective Idealism bridges the gap between Realism and Idealism. It accepts the reality of the external world (like Realism) but claims that this world is ultimately spiritual or mental in nature (like Idealism).

(Note: These are the exact questions translated from the “অনুশীলনী” section at the end of Block VI in the Assamese textbook).

Q1. Give the definition of Idealism.
Answer: Idealism is the epistemological theory which holds that the object of knowledge does not exist independently of the knower’s mind. According to this theory, mind, spirit, or consciousness is the ultimate reality, and the external world is dependent on the mind.

Q2. Who is the founder of Idealism in Western philosophy?
Answer: The ancient Greek philosopher Plato is considered the founder of Idealism in Western philosophy.

Q3. Who said “Existence depends on perception” (Esse est percipi)?
Answer: The Irish philosopher George Berkeley said “Esse est percipi” (To be is to be perceived).

Q4. How many types of Idealism are there and what are they?
Answer: Idealism is primarily of two types:

1. Subjective Idealism (Personal Idealism)
2. Objective Idealism (Absolute Idealism)

Q5. What do you mean by Subjective Idealism?
Answer: Subjective Idealism, advocated by George Berkeley, is the theory that the existence of the external world depends entirely on the perception of the individual mind (the subject). It claims that material objects are nothing but collections of ideas, and they exist only as long as they are perceived by a mind (“Esse est percipi”).

Q6. What is Objective Idealism?
Answer: Objective Idealism, advocated by Hegel, is the theory that the ultimate reality is the “Absolute Idea” or “Absolute Mind.” According to this view, the external physical world is not dependent on the individual human mind, but it is a real, objective manifestation of the universal Absolute Mind. It holds that thought and reality are fundamentally identical.

Short Answer Type (1-2 Marks)

1. What is the meaning of “Esse est percipi”? (AHSEC 2015, 2019) [1 Mark]
Ans: “Esse est percipi” is a Latin phrase that means “To be is to be perceived” or “Existence depends on perception.”

2. Who is the chief advocate of Objective Idealism? (AHSEC 2016, 2020) [1 Mark]
Ans: G.W.F. Hegel is the chief advocate of Objective Idealism.

Ans: This is the statement of G.W.F. Hegel.

5. What is Solipsism? (AHSEC 2021, 2025 Expected) [2 Marks]
Ans: Solipsism is the extreme philosophical idea that “only my mind exists,” and everything else, including the external world and other people, are just creations or ideas of my own mind. Berkeley’s Subjective Idealism is often criticized for leading to Solipsism.

Long Answer Type (4-6 Marks)

6. Explain Berkeley’s Subjective Idealism. (AHSEC 2015, 2020) [4 Marks]
Ans: Berkeley’s Subjective Idealism is based on the principle “Esse est percipi” (To be is to be perceived).

1. He argues that we only know our own ideas and sensations. Therefore, what we call physical objects (like a table or an apple) are simply collections of ideas in our mind.
2. He completely denies the existence of an independent, unthinking material substance (matter).
3. He argues that both primary qualities (shape, size) and secondary qualities (color, taste) are subjective and exist only in the mind.
4. To avoid the problem of objects disappearing when we don’t look at them, Berkeley introduces God (the Infinite Mind) who constantly perceives all things, keeping them in existence.

7. Explain Hegel’s Objective Idealism. (AHSEC 2016, 2022) [4 Marks]
Ans: Hegel’s Objective Idealism is based on the principle that “What is rational is actual and what is actual is rational.”

1. According to Hegel, the ultimate reality is the Absolute Idea, Absolute Mind, or Spirit.
2. The external physical world is not an illusion or a mere subjective idea of the human mind. Instead, it is a real, objective manifestation of the Absolute Idea.
3. Human minds are finite parts of this Infinite Absolute Mind.
4. Hegel reconciles Realism and Idealism by stating that the world is objectively real (Realism), but its fundamental nature is spiritual or mental (Idealism).

8. How does Berkeley refute Locke’s distinction between primary and secondary qualities? (AHSEC 2017, 2024) [4 Marks]
Ans: John Locke claimed that primary qualities (size, shape, motion) exist in the object, while secondary qualities (color, taste, smell) exist only in the mind. Berkeley refuted this by showing that primary qualities are just as mind-dependent as secondary qualities.
For example, the size of an object changes depending on how far away the observer is. The shape of a coin looks round from above but elliptical from an angle. Since primary qualities also change based on the observer’s position and perception, Berkeley concluded that all qualities are subjective ideas in the mind.

9. Why is Berkeley’s idealism called ‘Subjective’? (AHSEC 2018, 2023) [4 Marks]
Ans: Berkeley’s idealism is called ‘Subjective’ because it makes the existence of the entire external world dependent on the perception of the individual subject (the knower). According to him, an object has no independent, objective existence outside of a mind. A tree, a mountain, or a river exists only as a collection of ideas within a perceiving mind. Because reality is reduced to the subjective experiences and ideas of the perceiver, his theory is termed Subjective Idealism.

10. How does Berkeley use the concept of God to save his philosophy from Solipsism? (AHSEC 2019, 2025 Expected) [4 Marks]
Ans: Berkeley’s principle “To be is to be perceived” leads to a major problem: If a book only exists when I look at it, does it cease to exist when I leave the room? This leads to Solipsism (the belief that only my mind exists).
To solve this, Berkeley introduces the concept of the Infinite Mind, or God. He argues that even when no human being is perceiving an object, it continues to exist because it is constantly being perceived by the omnipresent mind of God. God’s continuous perception guarantees the permanence and order of the universe.

PART 3: 10 ADDITIONAL IMPORTANT Q&A FOR EXAMS

Short Answer Type (1-2 Marks)

1. What is the fundamental difference between Realism and Idealism? [2 Marks]
Ans: Realism holds that the object of knowledge exists independently of the knower’s mind (matter is real). Idealism holds that the object of knowledge is dependent on the knower’s mind (mind/spirit is the ultimate reality).

2. Name the three dialogues written by George Berkeley. [1 Mark]
Ans: “Three Dialogues between Hylas and Philonous” (1713).

3. What does Hegel mean by the “Absolute Idea”? [2 Marks]
Ans: By “Absolute Idea,” Hegel means the ultimate, infinite, and universal spiritual reality or consciousness. It is the supreme rational force from which the entire physical universe and all finite human minds emanate.

4. Does Hegel deny the reality of the external world? [1 Mark]
Ans: No, Hegel does not deny the reality of the external world. He accepts it as real, but views it as an objective expression of the Absolute Mind.

5. Why did Berkeley reject the concept of ‘Matter’? [2 Marks]
Ans: Berkeley rejected ‘matter’ because he believed we only ever experience ideas and sensations. An invisible, unthinking, and unperceivable substance called “matter” behind these sensations is an unnecessary and illogical assumption.

Long Answer Type (4-6 Marks)

6. Critically examine Berkeley’s Subjective Idealism. [6 Marks]
Ans: Berkeley’s Subjective Idealism (“Esse est percipi”) successfully highlights the active role of the mind in perception, but it faces severe criticisms:

1. Leads to Solipsism: If everything is just my idea, I have no logical reason to believe that other people or the world exist outside my mind.
2. Confuses the act of perception with the object: Berkeley confuses the mental act of perceiving a tree with the physical tree itself. The awareness of a tree is mental, but the tree itself is physical.
3. God as a convenient excuse: Berkeley brings in God merely as a “Deus ex machina” (a forced plot device) to explain why objects don’t disappear when we close our eyes. This makes his philosophical argument weak and reliant on theology.
4. Contrary to Common Sense: It goes against the universal human conviction that a solid, physical world exists independently of us.

7. Distinguish between Subjective Idealism and Objective Idealism. [4 Marks]
Ans:

1. Advocates: Subjective Idealism is advocated by Berkeley; Objective Idealism is advocated by Hegel.
2. Nature of Reality: Subjective Idealism reduces reality to the ideas of the individual, finite mind. Objective Idealism traces reality to a universal, infinite Absolute Mind.
3. Status of the World: In Subjective Idealism, the physical world has no objective existence; it is just a collection of personal ideas. In Objective Idealism, the physical world is objectively real, acting as the concrete manifestation of the Absolute Idea.
4. Approach: Subjective Idealism leans towards psychology and personal experience. Objective Idealism is highly logical, rational, and universal.

8. “What is rational is actual and what is actual is rational.” Explain this statement by Hegel. [4 Marks]
Ans: This famous statement by Hegel forms the core of his Objective Idealism.

• “What is rational is actual” means that the ultimate reality (the Absolute Idea) is pure reason or rationality, and this reason manifests itself in the actual, physical world.
• “What is actual is rational” means that everything that exists in the real world has a logical, rational structure because it is a product of the Absolute Mind.
  Therefore, there is no gap between thought (reason) and reality (the actual world). They are fundamentally identical.

9. How does Hegel’s Objective Idealism reconcile Realism and Idealism? [4 Marks]
Ans: Realism claims the external world is real and independent. Subjective Idealism claims the world is just an idea in the mind. Hegel reconciles these two extremes.
He agrees with Realism that the external world is objectively real and not just a figment of human imagination. However, he agrees with Idealism that the ultimate nature of this universe is not dead matter, but Spirit or Consciousness. By stating that the real, objective world is the physical expression of the Absolute Mind, Hegel successfully combines the truths of both Realism and Idealism.

10. If “Esse est percipi” is true, how do we explain the existence of things before humans evolved? [4 Marks]
Ans: If “To be is to be perceived” is strictly applied to human minds, it creates a scientific paradox: How did the Earth, dinosaurs, and stars exist before human beings evolved to perceive them?
Berkeley answers this by stating that human perception is not the only perception. Long before humans existed, the universe was constantly and eternally perceived by the Infinite Mind of God. Therefore, the universe existed as an idea in the mind of God before finite human minds were created to perceive it.
