Introduction to Philosophy/What is Philosophy
Definition & Meaning
- Philosophy is a broad field of knowledge in which the definition of knowledge itself is one of the subjects investigated. It spans the nature of the universe, the mind, and the body; the relationships between all three, and between people. Philosophy is a field of inquiry – the pursuit of wisdom; the predecessor and complement of science, developing the issues which underly science and pondering those questions which are beyond the scope of science.
- Using Philosophy
- The essence of philosophy is the study and development of fundamental ideas and methods that are not adequately addressed in specialized empirical disciplines, such as physics or history. As such, philosophy provides the foundations upon which all belief structures and fields of knowledge are built. It is responsible for the definitions of, and the approaches used to develop the theories of, such diverse fields as religion, language, science, law, psychology, mathematics, and politics. It also examines and develops its own structure and procedures, and when it does so is called metaphilosophy: the philosophy of philosophy.
Philosophy has a rich literary heritage, including the writings and teachings of profound thinkers from many cultures throughout history. Philosophers seek to understand the principles that underlie all knowledge and being. For this purpose, they develop methods of thinking, including logic, introspection, and meditation. Applying these methods, they investigate the most fundamental questions, such as "What is the nature of the universe?" (metaphysics), "What do we know, and how do we know it?" (epistemology), "What is the difference between good and evil?" (ethics), "What is beauty?" (aesthetics), and "What is the meaning of life?" (teleology).
- Philosophical Perspectives & Traditions
- 'Philosophy' translates literally from the original Greek as 'love of wisdom'. 'What is philosophy', is itself a philosophical question. This is a clue to the nature of philosophy. It is very general in scope; so general that it, perhaps uniquely among the disciplines, includes itself in its scope. What is clear is that philosophy is, in some sense, thinking about thinking.
In the analytic tradition of North America and the UK, philosophy is quite technical. It centres on logic and conceptual analysis. Topics at its centre include the theory of knowledge, ethics, the nature of language, and the nature of mind.
- Other traditions view philosophy as the study of the arts and science of life: a general theory and a commendation of way of life. In this sense, philosophy is concerned with the practical bits of how to live rather than a theoretical attempt to understand. "Don't try to figure out why - just try get on with things the way they are."
- In the analytic tradition, philosophy is something you do. In other traditions, philosophy is a body of knowledge to be mastered. It is possible to exaggerate these differences for when philosophy is not dogma each tradition pays some homage to the other.
- In the Western world, at one time the term 'philosophy' covered all disciplines. Over time, as the corpus of human knowledge grew, various disciplines emerged, each with their own methodologies and domains of study, and these disciplines became to a large extent autonomous. For example, if you go into a public library that uses the Dewey decimal classification system, you will find that psychology books have a classmark starting with 150 - right in the middle of the philosophy section. This is because at the time the system was created, in the latter half of the 19th century, psychology was only just beginning to emerge as a distinct discipline. Another example is the term 'natural philosophy', which was once used to mean science, or more particularly physics. By this view, what is called 'philosophy' at any time in history are those provinces of human knowledge which have not yet come of age, which not yet developed their own autonomous character and status.
- These independent disciplines do have their own philosophies; so there is a philosophy of science, a philosophy of mathematics, a philosophy of psychology, and so on. When studying in these areas, one looks at methodological issues or examines some of the core concepts of the discipline, as well as various ethical issues.
- There are domains which definitely belong in a philosophy department. Epistemology is concerned with 'how do I know what I know?', Ontology with 'what is there?', Ethics with 'how should one conduct oneself?'. Logic is concerned with proper reasoning. Many other disciplines exist within philosophy.
- The Branches of Philosophy
- In order to narrow the aims of discussion philosophy was broken into branches. Traditionally philosophy has been broken into four main branches; however we would like to add a fifth branch in our text
- Epistemology
- Metaphysics
- Metaphysics (derived from the Greek words "ta meta ta physika biblia") - meaning 'the book that follows the physics book'. It was the way students referred to a specific book in the works of Aristotle, and it was a book on First Philosophy. (The assumption that the word means "beyond physics" is misleading) Metaphysics is the branch of philosophy concerned with the study of "first principles" and "being" (ontology). In other words, Metaphysics is the study of the most general aspects of reality, such as substance, identity, the nature of the mind, and free will.
- Logic
- Logic (from Classical Greek λόγος (logos), originally meaning the word, or what is spoken, but coming to mean thought or reason) is most often said to be the study of arguments, although the exact definition of logic is a matter of controversy amongst philosophers (see below). However the subject is grounded, the task of the logician is the same: to advance an account of valid and fallacious inference to allow one to distinguish good from bad arguments.
- Ethics
- Ethics is a general term for what is often described as the "science (study) of morality". In philosophy, ethical behavior is that which is "good" or "right." The Western tradition of ethics is sometimes called moral philosophy.
- Other Branches
- Philosophy of Education: Fairly self-explanatory. A minor branch, mainly concerned with what is the correct way to educate a person. Classic works include Plato's Republic, Locke's Thoughts Concerning Education, and Rousseau's Emile.
- Philosophy of History: Fairly minor branch (not as minor as education), although highly important to Hegel and those who followed him, most notably Marx. It is the philosophical study of history, particularly concerned with the question whether history (i.e. the universe and/or humankind) is progressing towards a specific end? Hegel argued that it was, as did Marx. Classic works include Vico's New Science, and Hegel and Marx's works.
- Philosophy of Language: Ancient branch of philosophy which gained prominence in the last century under Wittgenstein. Basically concerned with how our languages affect our thought. Wittgenstein famously asserted that the limits of our languages mark the limits of our thought. Classic works include Plato's Cratylus, Locke's Essay, and Wittgenstein's Tractatus Logico-Philosophicus.
- Philosophy of Law: Also called Jurisprudence. Study of law attempting to discern what the best laws might be, how laws came into being in the first place, attempting to delimit human laws from natural laws, whether we should always obey the law, and so on. Law isn't often directly dealt with by philosophers, but much of political philosophy obviously has a bearing on it.
- Philosophy of Mathematics: Study of mathematics concerned with issues such as, is mathematics real or created by us, is it necessary to understand the world, do perfect mathematical forms exist in the real world, and so on. Principia Mathematica is almost certainly the most important work in this field.
- Philosophy of Mind: Study of the mind, attempting to ascertain exactly what the mind is, how it interacts with our body, do other minds exist, how does it work, and so on. Probably the most popular branch of philosophy right now, it has expanded to include issues of AI. Classic works include Plato's Republic and Wittgenstein's Philosophical Investigations, although every major philosopher has had some opinion at least on what the mind is and how it works.
- Philosophy of Politics: Closely related to ethics, this is a study of government and nations, particularly how they came about, what makes good governments, what obligations citizens have towards their government, and so on. Classic works include Plato's Republic, Hobbes' Leviathan, Locke's Two Treatises, and J.S. Mill's On Liberty.
- Philosophy of Religion: Theology is concerned with the study of God, recommending the best religious practises, how our religion should shape our life, and so on. Philosophy of religion is concerned with much the same issues, but where Theology uses religious works, like the Bible, as it's authority, philosophy likes to use reason as the ultimate authority.
- Philosophy of Science: Study of science concerned with whether scientific knowledge can be said to be certain, how we obtain it, can science really explain everything, does causation really exist, can every event in the universe be described in terms of physics and so on. Also popular in recent times, classic works include Hume's Treatise on Human Nature, Kripke's Naming and Necessity, Kuhn's Structure of Scientific Revolutions.
- Doing Philosophy
- Many fields can be studied and learned without ever actually working with the tools in the field. For instance, chemistry can be learned in depth without ever picking up a test tube or mixing ionic compounds. Philosophy, however, is more about the methodology behind deriving answers than it is about the answers themselves. As such, a student studying philosophy must use the methodology of philosophy on the philosophy they are learning as they are learning it. Doing philosophy involves asking the right questions, critically examining the work of previous philosophers, truly understanding the works and the reasoning behind the works, and possibly building on the works of previous philosophers by expanding or testing this methodology.
