Introduction to Philosophy
Definitions and Scope of Philosophy
Philosophy: "love of wisdom,"
Intellectual discipline that seeks to understand fundamental truths about the world, human
existence, and the relationships between them
Greek words "philo" (love) and "sophia" (wisdom)
Evolved over millennia
Addresses profound questions: Reality, knowledge, morality, and, human condition
Involves the critical examination of concepts, beliefs, and arguments
Engages with abstract reasoning and logical analysis
Aims to clarify thoughts, explore the nature of existence, and provide frameworks for
understanding the world
Extends across various branches, each addressing different aspects of life and knowledge.
Metaphysics: Explores the nature of reality, existence, and the universe
Metaphysical questions: Delve into what it means for something to exist, the nature of objects,
and the relationship between mind and matter.
Examines concepts like: Being, time, space, causality, and the nature of the self.
Epistemology: Epistēmē (“knowledge”) and logos (“reason”)
Study of nature, origin, and limits of human knowledge
Also referred to as the theory of knowledge.
Origins of Philosophy –
Can be traced back to ancient civilizations, where human beings first began to engage in
systematic thinking about the nature of existence, reality, and knowledge
Represents a fundamental aspect of human curiosity and intellectual exploration
Intertwined with the historical, cultural, and intellectual contexts of early human societies
Particularly in ancient Greece, India, and China
Ancient Greece: The Birthplace of Western Philosophy
Originated in ancient Greece, around the 6th century BCE
Pre-Socratic philosophers
include Thales, Anaximander, and Heraclitus
Sought to explain the natural world through rational inquiry rather than mythological
narratives
Thales of Miletus, often regarded as the first philosopher, proposed that water was the
fundamental substance underlying all of reality
His approach marked a significant departure from traditional mythological explanations and
set the stage for a more systematic and critical examination of the world.
The Pre-Socratics laid the groundwork for the development of more sophisticated
philosophical systems
Socrates, Plato, and Aristotle, the most prominent figures of classical Greek philosophy, further
advanced philosophical thought
Socrates emphasized the importance of ethical inquiry and self-examination
1
famously declared that "the unexamined life is not worth living."
Plato, a student of Socrates, developed the theory of Forms
posited that the physical world is a mere shadow of a higher, unchanging reality
Aristotle, in turn, made significant contributions to logic, metaphysics, ethics, and natural
sciences
Shaped the course of Western philosophy for centuries to come.
Ancient India: The Vedic Tradition and Beyond
philosophical thought within the context of the Vedic tradition
The Vedas formed the basis of early Indian philosophy
The Upanishads, composed between the 8th and 6th centuries BCE
Represent a key philosophical development within the Vedic tradition
These texts explore profound questions about the nature of reality, the self, and the ultimate
purpose of life
Buddhism
founded by Siddhartha Gautama in the 5th century BCE,
Emphasized the impermanence of all things, the nature of suffering
Path to enlightenment through ethical conduct, meditation, and wisdom
Four Noble Truths and the Eightfold Path
Offered a systematic approach to understanding and overcoming human suffering.
Ancient China: Confucianism and Daoism
Philosophy emerged within the context of social and political upheaval
Confucius (551–479 BCE) and Laozi (6th century BCE) are the two most influential figures in
early Chinese philosophy
Confucianism emphasized the importance of morality, social harmony, and respect for
tradition
Teachings on virtue, ethics, and proper conduct became deeply ingrained in Chinese culture
Influenced East Asian thought for millennia.
Daoism, associated with Laozi and the text "Dao De Jing," offered a contrasting perspective.
Daoism emphasizes living in harmony with the Dao, the fundamental principle that underlies
the universe.
Advocates simplicity, spontaneity, and non-action (wu wei) as means to align oneself with the
natural order of things.
The four primary perspectives or branches of philosophy are:
Metaphysics:
Deals with the nature of reality and existence.
Explores questions about what is real, what kinds of things exist, and the nature of being
Focus on concepts such as substance, time, space, causality
Relationship between mind and body.

Epistemology:
Study of knowledge, belief, and the nature of truth
What is knowledge? How do we know what we know? What are the limits of human
understanding?
Examine the sources and validity of knowledge
Including perception, reasoning, memory, and testimony.
Ethics:
study of values and principles that guide human conduct
Questions of right and wrong, good and evil
Normative ethics; Meta-ethics (Nature of moral judgments); Applied ethics (Real-world issues).
Aesthetics:
Deals with the nature of beauty, art, and taste
Examines what makes something aesthetically pleasing, the nature of artistic expression, and
how humans perceive and respond to beauty
Explores the philosophy of art, including the interpretation and evaluation of works of art.
Follows a systematic exploration of fundamental questions about reality, knowledge, ethics,
and beauty.
Understanding Epistemology: The Study of Knowledge
Greek words "epistēmē" (knowledge) and "logos" (study)
Branch of philosophy concerned with the nature, scope, and limits of human knowledge
Asks foundational questions: What knowledge is? how it is acquired? What extent it is possible?
Addresses a variety of complex issues: Definition of knowledge; Methods to justify our beliefs;
Central area of philosophical inquiry.
The Nature of Knowledge
At the heart of epistemology is the question, "What is knowledge?"
Knowledge: "justified true belief."
three conditions must be met:
1. the proposition must be true
2. individual must believe it, and
3. there must be sufficient justification for the belief
Gettier problem: Edmund Gettier, published a paper questioning whether justified true belief is
sufficient for knowledge
Demonstrated that individuals had justified true beliefs that nonetheless seemed not to
constitute knowledge
3
Resulted in debates: whether additional conditions are necessary for a belief to qualify as
knowledge.
Sources and Justification of Knowledge
origin of knowledge: Another critical concern
Epistemologists study various sources of knowledge, such as perception, reason, memory, and
testimony
Source Reliability;
Rationalism and empiricism are two dominant schools of thought
Rationalists argue: Reason and innate ideas are the primary sources of knowledge
Certain concepts and knowledge exist independent of experience; can be accessed through
reasoning.
Empiricists contend:All knowledge comes from sensory experience
According to them, the mind at birth is a blank slate (tabula rasa), and
knowledge is built up from experiences over time.
Justification: Central to epistemology
Theories of justification: Foundationalism, coherentism, and reliabilism
1. Foundationalism: Basic beliefs that do not require justification
2. Coherentism: Beliefs are justified if they cohere or fit together in mutually supportive network
3. Reliabilism: Beliefs are justified if they are produced by a reliable cognitive process.
Skepticism and the Limits of Knowledge
Skepticism: the view that certain or all knowledge is impossible
Skeptical arguments challenge the possibility of having any knowledge
often by questioning the reliability of our cognitive faculties or the truth of our beliefs
Radical skepticism questions whether we can know anything at all
leading to the famous Cartesian doubt
Descartes questions the existence of everything except the self
Skepticism raises challenging questions
Pushes philosophers to clarify the nature of knowledge and the standards for justifying beliefs.
Contextualism: Standards for knowledge may vary depending on the context.
