What is Philosophy – Definition, Methods, Types

What is Philosophy



Philosophy is the study of the fundamental nature of knowledge, reality, and existence. It is characterized by a questioning approach to life and a critical examination of ethical and moral issues.

Philosophers use reason and logic to analyze arguments and to uncover truth. They often ask questions such as:

  • What is the meaning of life?
  • What is the nature of reality?
  • How should we live our lives?

While philosophy may seem like a complex and difficult subject, it can be useful in our everyday lives. By learning to think critically and analytically, we can better understand the world around us and make more informed decisions.

History of Philosophy

In the West, philosophy began in the 6th century BC with the Pre-Socratics. These were mostly from Miletus on the Ionian coast of Asia Minor. Thales is usually considered the first Western philosopher and said that everything was made of water. Anaximander believed that a single underlying substance gave rise to everything that exists. Heraclitus believed that change was the only constant in the universe. Parmenides believed that reality is unchanging and static.

The next major period in Western philosophy was Socrates, Plato, and Aristotle in classical Greece. Socrates was a moral philosopher who emphasized ethics and personal virtue. Plato founded the Academy, one of the first institutions of higher learning in Western culture. He also wrote dialogues, many of which feature Socrates as a character.

Western Philosophy

The Western philosophical tradition began in ancient Greece and has been continued and developed by philosophers throughout the ages.
Some of the most famous Western philosophers include Socrates, Plato, Aristotle, René Descartes, Immanuel Kant, and John Stuart Mill. These thinkers have had a profound influence on Western culture and thought.

Western philosophy is characterized by its focus on reason and logical argument. This tradition has produced some of the greatest minds in history and has helped to shape modern society.

Middle Eastern Philosophy

Middle Eastern philosophy is a field of study that dates back thousands of years. It is a rich and complex body of thought that has influenced many other philosophical traditions.

Some of the most famous Middle Eastern philosophers include Avicenna, Averroes, and Al-Ghazali. These thinkers made significant contributions to our understanding of metaphysics, epistemology, and ethics.

Middle Eastern philosophy continues to be an important area of research for scholars today. It provides insights into the history and culture of the region, as well as offering new perspectives on perennial philosophical problems.

Eastern philosophy

Eastern philosophy is a rich and complex tradition that has its origins in the ancient cultures of Asia. Its main schools are Confucianism, Taoism, Buddhism, and Zen Buddhism.

Eastern philosophy stresses the importance of inner peace and harmony. Its teachings can be applied to our everyday lives, helping us to find balance and perspective. By exploring the ancient wisdom of these philosophies, we can gain a deeper understanding of ourselves and the world around us.

African philosophy

African philosophy is the philosophical discourse of Africa, including both traditional African philosophy and contemporary African philosophy.

Traditional African philosophy is oral and takes the form of storytelling, proverbs, and sayings. It is often concerned with cosmology, religion, and ethics. Some of the best-known traditional African philosophers are Cheikh Anta Diop, Placide Tempels, Julius Nyerere, and Kwame Nkrumah.

Contemporary African philosophy is a broad field that includes feminist philosophy, postcolonial philosophy, and philosophical traditions from specific countries such as Ghanaian or Kenyan philosophy. Some of the most influential contemporary African philosophers are Alain Locke, Frantz Fanon, Lewis Gordon, Kwasi Wiredu, and Tsenay Serequeberhan.

Indigenous American philosophy

Indigenous American philosophy refers to the intellectual traditions of the indigenous peoples of the Americas. This includes a wide range of philosophical perspectives from traditional Native American beliefs to more modern, critical engagements with Euro-American thought.

Indigenous American philosophy has often been devalued and marginalized within mainstream philosophical discourse. However, there is a growing appreciation for the unique insights offered by these perspectives. Indigenous philosophers are re-claiming their place within the philosophical canon and contributing to important conversations about ethics, epistemology, and metaphysics.

Branches of Philosophy

The following are branches of Philosophy. These are also known as types of Philosophy.

  • Aesthetics
  • Ethics
  • Epistemology
  • Metaphysics
  • Logic
  • Mind and language
  • Philosophy of science
  • Political philosophy
  • Philosophy of religion
  • Metaphilosophy


Aesthetics is the branch of philosophy that deals with the nature and appreciation of art, beauty, and taste. It covers both the objective and subjective aspects of these concepts. Aesthetics is a critical part of everyday life, as we make decisions based on our aesthetic preferences all the time.

Some philosophers argue that there is an objective standard for aesthetics, while others contend that it is entirely subjective. Either way, it is clear that aesthetics play a significant role in our lives.


Ethics is a branch of philosophy that involves systematizing, defending, and recommending concepts of right and wrong conduct. The field of ethics, along with aesthetics, concerns matters of value, and thus comprises the branch of philosophy called axiology.

Philosophers today usually divide ethical theories into three major categories:

  • Meta-Ethics
  • Normative Ethics
  • Applied Ethics

Meta-ethics investigates the origin and meaning of ethical concepts.

Normative Ethics

Normative ethics deals with the content of moral judgments and prescriptions (that is, what we ought to do) and with justifications for particular kinds of action.

Applied Ethics

Applied ethics applies normative ethical theories to specific controversial issues, such as abortion, animal rights, euthanasia, environmental pollution, genetic engineering, pornography, racism, social justice (affirmative action), war and capital punishment.


Epistemology is the study of knowledge and justified belief. As the study of knowledge, epistemology is concerned with the following questions:

  • What are the necessary and sufficient conditions of knowledge?
  • What are its sources?
  • What is its structure, and what are its limits?

As the study of justified belief, epistemology is concerned with questions about the nature and justification of belief, doubt, and other attitudes that pertain to believing.


Metaphysics is the study of the fundamental nature of reality and existence. It attempts to answer the question “What is there?”

Metaphysics can be divided into three branches:

  • Ontology
  • Cosmology
  • Eschatology

Ontology deals with the nature of existence and asks questions such as “What is a thing?” and “What is it like to be a thing?”


Cosmology deals with the origin and structure of the universe, including questions about time, space, matter, energy, and life.


Eschatology deals with the final fate of reality, including questions about death, immortality, heaven, hell, and reincarnation.


Logic is the study of the principles of correct reasoning. Logic is concerned with the methods and criteria we use to distinguish between good and bad arguments. Good arguments are those that are valid and sound; they are strong enough to be convincing.

Bad arguments, on the other hand, are either invalid or unsound. Invalid arguments are simply not strong enough to be convincing, while unsound arguments may be strong but contain one or more false premises.

The study of logic is therefore important not only for philosophers but for anyone who wants to learn how to reason correctly. After all, if we can’t even tell when an argument is good or bad, how can we hope to understand complex philosophical questions?

Mind and Language

Mind and Language are studied together because it is difficult to study one without the other. The relationship between mind and language is complex, but philosophers have made some progress in understanding it.
One way to think about the relationship between mind and language is in terms of meaning. Meaning is what we use words to talk about. It is the content of our thoughts. When we hear a word, we understand its meaning. But where does that meaning come from?

Some philosophers think that meaning is a mental thing. That is, when we hear a word, we access its meaning from our mind. This view is called mentalism. Other philosophers think that meaning is a linguistic thing. That is, the meaning of a word is determined by its place in the language system. This view is called linguistic determinism.

Philosophy of Science

Philosophy of science is the study of the assumptions, foundations, and implications of science. It is not a separate field of study, but rather an approach that can be applied to all scientific disciplines. The philosophy of science is concerned with the nature of scientific theories, the methods used to test them, and the implications of those theories.

Political Philosophy

Political philosophy is a branch of philosophy that deals with the concepts and theories behind the operation of political systems. It can be applied to both real-world and imaginary situations, and is often used to analyze and critique political policies.

Philosophy of Religion

Philosophy of religion is the philosophical study of the nature and scope of religion, including the concepts of God, religious experience, and religious language. It also encompasses the ethical implications of religious belief and practice.


Metaphilosophy is the study of the nature, aims, and methods of philosophy. It is difficult to define metaphilosophy precisely, because it can be used to refer to a number of different things.

Sometimes it is used to refer to the study of the fundamental questions that philosophers ask about the nature of philosophy itself. For example,

  • what is the nature of reality?
  • What is the relationship between mind and body?
  • What is the difference between right and wrong?
  • Other times, it is used more broadly to refer to any attempt to reflect on or analyze philosophical methods and assumptions.

In general, metaphilosophers are interested in exploring the assumptions that underlie philosophical thought. They want to know what makes something a philosophical problem and how we should go about solving it. Metaphilosophers also often ask questions about the limits of philosophy.

Philosophical Methodology

Philosophical methodology is the study of how to do philosophy. It is concerned with the ways in which philosophers go about their business, and with the criteria, they use to determine whether something is good philosophy or not. Philosophical Research Methods are as follows:

  • Methodological skepticism
  • Geometrical method
  • Phenomenological method
  • Verificationism
  • Conceptual analysis
  • Common sense
  • Ordinary language philosophy
  • Intuition and thought experiments
  • Reflective equilibrium
  • Pragmatic method
  • Transcendental method
  • Experimental Philosophy

Methodological Skepticism

Methodological skepticism is a philosophical position that holds that certain claims particularly those made in the sciences are not necessarily true or reliable, and should therefore be subjected to further scrutiny and testing.

The idea of methodological skepticism can be traced back to the ancient Greek philosopher Pyrrho, who is credited with originating the concept. Pyrrho argued that because it is impossible to know anything for certain, we should suspend judgment on all matters of knowledge. This view was later adopted by the Skeptical Academy, a school of thought founded in the 3rd century BCE.

Geometrical method

The geometrical method is a method of reasoning that uses geometry as its basis. This method was developed by the Greek philosopher Euclid and has been used in many different fields, including philosophy. The geometrical method is based on the idea that certain truths can be proved by means of geometric constructions. This method has been used to prove a wide variety of philosophical principles, including the existence of God and the immortality of the soul.

Phenomenological method

Phenomenological method is a research method used in philosophy. It is a way of investigating phenomena, or events, by studying them firsthand. This means that phenomenological research is subjective, and it relies on the researcher’s own experiences and observations.

The phenomenological method is used to gain a deep understanding of a certain phenomenon. This is done by studying the phenomenon in its natural environment and observing it firsthand. The researcher then records his or her observations and reflections on the phenomenon.


In philosophy, verificationism is the view that a statement must be capable of being verified in order to be meaningful. This means that statements which cannot be verified through observation or experience are not meaningful and therefore do not need to be considered when engaging in philosophical discussion.

Conceptual analysis

Conceptual analysis is the process of breaking down an abstract concept into smaller, more manageable parts. It is a tool that philosophers use to understand complex ideas and to make them easier to discuss and debate.

Common sense

Common sense is our basic ability to perceive, understand, and judge things correctly. It’s the voice in our head that tells us whether something feels right or wrong.

Unfortunately, common sense isn’t always correct. We can make bad decisions based on our gut feelings, and we can also be misled by others who may not have our best interests at heart. That’s why it’s important to use our common sense wisely and critically.

Ordinary language philosophy

Ordinary language philosophy is a school of thought that emphasizes the study of language and its relation to the problems of philosophy. The school is associated with such philosophers as Ludwig Wittgenstein, J. L. Austin, and Gilbert Ryle.

Intuition and thought experiments

Intuition and thought experiments have been used as research methods in philosophy for centuries. Intuition is defined as the ability to understand something immediately, without the need for conscious reasoning. A thought experiment is an experiment that is performed in one’s mind, rather than in a physical setting.

Thought experiments can be used to investigate a wide variety of philosophical questions. For example, René Descartes’ famous thought experiment of the evil demon proves that we cannot trust our senses, because it is possible that they are being deceived by an evil demon.

Reflective equilibrium

The reflective equilibrium is a process of reflection and revision that is used to reach a balance between our beliefs and our considered judgments about particular cases. We can think of this equilibrium as a set of beliefs that are mutually consistent with each other.

Pragmatic method

In philosophy, the pragmatic method is a way of approaching ideas and events. It is based on the idea that the best way to understand something is to examine it in terms of its practical consequences.

The pragmatic method is not just a way of looking at things; it is also a way of doing philosophy. The goal of the pragmatist philosopher is not to find truth, but to find what works.

Transcendental method

In philosophy, the transcendental method is a method of inquiry that seeks to go beyond the limits of human reason in order to gain knowledge about things that are not accessible to our ordinary ways of knowing. This includes things like the nature of reality, the existence of God, and the nature of consciousness.

The transcendental method is often associated with Immanuel Kant, who used it to argue for the existence of things like space and time as a priori categories of human understanding. However, other philosophers have also employed the transcendental method, including Hegel, Husserl, and Heidegger.

Experimental Philosophy

Experimental philosophy has been on the rise in recent years as a method for doing philosophy. Its proponents argue that it can help to address some of the long-standing problems in philosophy, such as the problem of skepticism. Skepticism is the view that we cannot know anything for sure. Experimental philosophers have conducted a number of experiments that they say show that people do not really think that way.

One well-known experiment is the “knower’s paradox” experiment, in which people are asked whether they would rather know the truth or believe what they want to believe. The vast majority of people say they would rather know the truth, even if it is unpleasant. This shows that people do not really doubt everything, as skeptics claim.

Purpose of Philosophy

The main purpose of philosophy is to analyze and study different ideas, thought processes, beliefs, arguments, justifications, etc. in order to gain a better understanding of them. It helps us think more critically and deeply about various topics and issues in order to form our own opinions and beliefs about them. Additionally, philosophy can also be used as a tool for solving practical problems or resolving differences between people.
