Welcome to the I Can't Sleep Podcast,
Where I help you drift off one fact at a time.
I'm your host,
Benjamin Boster.
And today's episode is about philosophy.
Philosophy,
From ancient Greek φιλοσοφία,
Literally love of wisdom,
Is a systematic study of general and fundamental questions concerning topics like existence,
Knowledge,
Mind,
Reason,
Language,
And value.
It is a rational and critical inquiry that reflects on its methods and assumptions.
Historically,
Many of the individual sciences,
Such as physics and psychology,
Formed part of philosophy.
However,
They are considered separate academic disciplines in the modern sense of the term.
Influential traditions in the history of philosophy include Western,
Arabic-Persian,
Indian,
And Chinese philosophy.
Western philosophy originated in ancient Greece and covers a wide area of philosophical subfields.
A central topic in Arabic-Persian philosophy is the relation between reason and revelation.
Indian philosophy combines the spiritual problem of how to reach enlightenment with the exploration of the nature of reality and the ways of arriving at knowledge.
Chinese philosophy focuses principally on practical issues about right social conduct,
Government,
And self-cultivation.
Major branches of philosophy are epistemology,
Ethics,
Logic,
And metaphysics.
Epistemology studies what knowledge is,
And how to acquire it.
Ethics investigates moral principles and what constitutes right conduct.
Logic is the study of correct reasoning and explores how good arguments can be distinguished from bad ones.
Metaphysics examines the most general features of reality,
Existence,
Objects,
And properties.
Other sub-fields are Aesthetics,
Philosophy of Language,
Philosophy of Mind,
Philosophy of Mathematics,
Philosophy of Science,
Philosophy of Religion,
Philosophy of History,
And Political Philosophy.
Within each branch,
There are competing schools of philosophy that promote different principles,
Theories,
Or methods.
Philosophers use a great variety of methods to arrive at philosophical knowledge.
They include conceptual analysis,
Reliance on common sense and intuitions,
Use of thought experiments,
Analysis of ordinary language,
Description of experience,
And critical questioning.
Many scientific academic disciplines have associated philosophical subfields like philosophy of physics and philosophy of biology,
Examining their fundamental concepts,
Methods,
Assumptions and implications.
Philosophy is related to and informs many other fields,
Such as law,
Business,
And journalism,
Providing an interdisciplinary perspective and addressing their ethical questions.
Before the modern age,
The term philosophy was used in a wide sense.
It included most forms of rational inquiry,
Such as the individual sciences,
As its sub-disciplines.
For instance,
Natural philosophy was a major branch of philosophy.
This branch of philosophy encompassed a wide range of fields,
Including disciplines like physics,
Chemistry,
And biology.
The meaning of philosophy changed toward the end of the modern period when it acquired the more narrow meaning common today.
In this new sense,
The term is mainly associated with disciplines like metaphysics,
Epistemology,
And ethics.
Among other topics,
It covers the rational study of reality,
Knowledge,
And values.
It is distinguished from other disciplines of rational inquiry,
Such as the empirical sciences and mathematics.
The practice of philosophy is characterized by several general features.
It is a form of rational inquiry.
It aims to be systematic.
And it tends to critically reflect on its own methods and presuppositions.
It requires attentively thinking long and carefully about the provocative,
Vexing,
And enduring problems central to the human condition.
The philosophical pursuit of wisdom involves asking general and fundamental questions.
It often does not result in straightforward answers,
But may help a person to better understand the topic,
Examine their life,
Dispel confusion,
And overcome prejudices and self-deceptive ideas associated with common sense.
For example,
Socrates stated that the unexamined life is not worth living to highlight the role of philosophical inquiry in understanding one's own existence.
And according to Bertrand Russell,
The man who has no tincture of philosophy goes through life imprisoned in the prejudices derived from common sense,
From the habitual beliefs of his age or his nation,
And from convictions which have grown up in his mind without the cooperation or consent of his deliberate reasons.
Some definitions characterize philosophy in relation to its method,
Like pure reasoning.
Others focus on its topic,
For example,
As the study of the biggest patterns of the world as a whole,
Or as the attempt to answer the big questions.
Such an approach is pursued by Immanuel Kant,
Who holds that the task of philosophy is united by four questions.
What can I know?
What should I do?
What may I hope?
And what is the human being?
Both approaches have the problem that they are usually either too wide by including non-philosophical disciplines,
Or too narrow by excluding some philosophical sub-disciplines.
Many definitions of philosophy emphasize its intimate relation to science.
In this sense,
Philosophy is sometimes understood as a proper science in its own right.
According to some naturalistic philosophers,
Such as W.
V.
O.
Quinn,
Philosophy is an empirical yet abstract science that is concerned with wide-ranging empirical patterns instead of particular observations.
Science-based definitions usually face the problem of explaining why philosophy,
In its long history,
Has not progressed to the same extent or in the same way as the sciences.
This problem is avoided by seeing philosophy as an immature or provisional science,
Whose sub-disciplines cease to be philosophy once they have fully developed.
In this sense,
Philosophy is sometimes described as the midwife of the sciences.
Other definitions focus on the contrast between science and philosophy.
A common theme among many such conceptions is that philosophy is concerned with meaning,
Understanding,
Or the clarification of language.
According to one view,
Philosophy is conceptual analysis,
Which involves finding the necessary and sufficient conditions for the application of concepts.
Another definition characterizes philosophy as thinking about thinking,
To emphasize its self-critical reflective nature.
A further approach presents philosophy as a linguistic therapy.
According to Ludwig Wittgenstein,
For instance,
Philosophy aims at dispelling misunderstandings to which humans are susceptible due to the confusing structure of ordinary language.
Phenomenologists,
Such as Edmund Husserl,
Characterize philosophy as a rigorous science investigating essences.
They practice a radical suspension of theoretical assumptions about reality to get back to the things themselves,
That is,
As originally given in experience.
They contend that this base level of experience provides a foundation for higher-order theoretical knowledge,
And that one needs to understand the former to understand the latter.
An early approach found in ancient Greek and Roman philosophy is that philosophy is the spiritual practice of developing one's rational capacities.
This practice is an expression of the philosopher's love of wisdom and has the aim of improving one's well-being by leading a reflective life.
For example,
The Stoics saw philosophy as an exercise to train the mind and thereby achieve eudaimonia and flourish in life.
Epistemology is the branch of philosophy that studies knowledge.
It is also known as Theory of Knowledge and aims to understand what knowledge is,
How it arises,
What its limits are,
And what value it has.
It further examines the nature of truth,
Belief,
Justification,
And rationality.
Some of the questions addressed by epistemologists include,
By what methods can one acquire knowledge?
How is truth established?
And can we prove causal relations?
One area in epistemology is the analysis of knowledge.
It assumes that declarative knowledge is a combination of different parts and attempts to identify what those parts are.
An influential theory in this area claims that knowledge has three components.
It is a belief that is justified and true.
This theory is controversial,
And the difficulties associated with it are known as the Get-Here Problem.
Alternative views state that knowledge requires additional components,
Like the absence of luck.
Different components,
Like the manifestation of cognitive virtues instead of justification.
Or they deny that knowledge can be analyzed in terms of other phenomena.
Another area in epistemology asks how people acquire knowledge.
Often discussed sources of knowledge are perception,
Introspection,
Memory,
Inference,
And testimony.
According to empiricists,
All knowledge is based on some form of experience.
Rationalists reject this view and hold that some forms of knowledge,
Like innate knowledge,
Are not acquired through experience.
The regress problem is a common issue in relation to the sources of knowledge and the justification they offer.
It is based on the idea that beliefs require some kind of reason or evidence to be justified.
The problem is that the source of justification may itself be in need of another source of justification.
This leads to an infinite regress or circular reasoning.
Foundationalists avoid this conclusion by arguing that some sources can provide justification without requiring justification themselves.
Another solution is presented by Coherentus,
Who state that a belief is justified if it coheres with other beliefs of the person.
Essex,
Also known as moral philosophy,
Studies what constitutes right conduct.
It is also concerned with the moral evaluation of character traits and institutions.
It explores what the standards of morality are and how to live a good life.
Philosophical ethics addresses such basic questions as,
Are moral obligations relative?
What has priority,
Well-being,
Or obligation?
And what gives life meaning?
The main branches of Ethics are Metaethics,
Normative Ethics,
And Applied Ethics.
Metaethics asks abstract questions about the nature and sources of morality.
It analyzes the meaning of ethical concepts like right action and obligation.
It also investigates whether ethical theories can be true in an absolute sense,
And how to acquire knowledge of them.
Normative ethics encompasses general theories of how to distinguish between right and wrong conduct.
It helps guide moral decisions by examining what moral obligations and rights people have.
Applied ethics studies the consequences of the general theories developed by normative ethics in specific situations,
For example,
In the workplace or for medical treatments.
Logic is the study of correct reasoning.
It aims to understand how to distinguish good from bad arguments.
It is usually divided into formal and informal logic.
Formal logic uses artificial languages with a precise symbolic representation to investigate arguments.
In its search for extra criteria,
It examines the structure of arguments to determine whether they are correct or incorrect.
Informal logic uses non-formal criteria and standards to assess the correctness of arguments.
It relies on additional factors such as content and context.
Logic also investigates incorrect forms of reasoning.
They are called fallacies,
And are divided into formal and informal fallacies,
Based on whether the source of the error lies only in the form of the argument,
Or also in its content and context.
Metaphysics is the study of the most general features of reality,
Such as existence,
Objects and their properties,
Poles and their parts,
Space and time,
Events,
And causation.
There are disagreements about the precise definition of a term,
And its meaning has changed throughout the ages.
Metaphysicians attempt to answer basic questions including,
Why is there something rather than nothing?
Of what does reality ultimately consist?
And are humans free.
An important area in metaphysics is ontology.
Some Zerus identify it with general metaphysics.
Ontology investigates concepts like being,
Becoming,
And reality.
It studies the categories of being and asks what exists on the most fundamental level.
Another subfield of metaphysics is philosophical cosmology.
It is interested in the essence of the world as a whole.
It asks questions including whether the universe has a beginning and an end,
And whether it was created by something else.
A key topic in metaphysics concerns a question of whether reality only consists of physical things like matter and energy.
Alternative suggestions are that mental entities,
Such as souls and experiences,
And abstract entities,
Such as numbers,
Exist apart from physical things.
Another topic in metaphysics concerns the problem of identity.
One question is how much an entity can change while still remaining the same entity.
According to one view,
Entities have essential and accidental features.
They can change their accidental features,
But they cease to be the same entity if they lose an essential feature.
A central distinction in metaphysics is between particulars and universals.
Universals like the color red can exist at different locations at the same time.
This is not the case for particulars,
Including individual persons or specific objects.
Other metaphysical questions are whether the past fully determines the present,
And what implications this would have for the existence of free will.
Aesthetics in the philosophical sense is the field that studies the nature and appreciation of beauty and other aesthetic properties,
Like the sublime.
Although it is often treated together with the philosophy of art,
Aesthetics is a broader category that encompasses other aspects of experience,
Such as natural beauty.
In a more general sense,
Aesthetics is critical reflection on art,
Culture,
And nature.
A key question in aesthetics is whether beauty is an objective feature of entities or a subjective aspect of experience.
Aesthetic philosophers also investigate the nature of aesthetic experiences and judgments.
Further topics include the essence of works of art and the processes involved in creating them.
The philosophy of language studies the nature and function of language.
It examines the concepts of meaning,
Reference,
And truth.
It aims to answer questions such as how words are related to things,
And how language affects human thought and understanding.
It is closely related to the disciplines of logic and linguistics.
The philosophy of language rose to particular prominence in the early 20th century in analytic philosophy due to the works of Frege and Russell.
One of its central topics is to understand how sentences get their meaning.
There are two broad theoretical camps,
Those emphasizing the formal truth conditions of sentences,
And those investigating circumstances that determine when it is suitable to use a sentence,
The latter of which is associated with speech-act theory.
The philosophy of mind studies the nature of mental phenomena and how they are related to the physical world.
It aims to understand different types of conscious and unconscious mental states,
Like beliefs,
Desires,
Intentions,
Feelings,
Sensations,
And free will.
An influential intuition in the philosophy of mind is that there is a distinction between the inner experience of objects and their existence in the external world.
The mind-body problem is the problem of explaining how these two types of thing,
Mind and matter,
Are related.
The main traditional responses are materialism,
Which assumes that matter is more fundamental,
Idealism,
Which assumes that mind is more fundamental,
And dualism,
Which assumes that mind and matter are distinct types of entities.
In contemporary philosophy,
Another common view is functionalism,
Which understands mental states in terms of the functional or causal roles they play.
The mind-body problem is closely related to the hard problem of consciousness,
Which asks how the physical brain can produce qualitatively subjective experiences.
The philosophy of religion investigates the basic concepts,
Assumptions,
And arguments associated with religion.
It critically reflects on what religion is,
How to define the divine,
And whether one or more gods exist.
It also includes the discussion of worldviews that reject religious doctrines.
Further questions addressed by the philosophy of religion are,
How are we to interpret religious language,
If not literally?
Is divine omniscience compatible with free will?
And,
Are the great variety of world religions in some way compatible,
In spite of their apparently contradictory theological claims?
It includes topics from nearly all branches of philosophy.
It differs from theology since theological debates typically take place within one religious tradition,
Whereas debates in the philosophy of religion transcend any particular set of theological assumptions.
The philosophy of science examines the fundamental concepts,
Assumptions,
And problems associated with science.
It reflects on what science is and how to distinguish it from pseudoscience.
It investigates the methods employed by scientists,
How their application can result in knowledge,
And on what assumptions they are based.
It also studies the purpose and implications of science.
Some of its questions are,
What counts as an adequate explanation?
Is a scientific law anything more than a description of a regularity?
And can some special sciences be explained entirely in the terms of a more general science?
It is a vast field that is commonly divided into the philosophy of the natural sciences and the philosophy of the social sciences,
With further subdivisions for each of the individual sciences under these headings.
How these branches are related to one another is also a question in the philosophy of science.
Many of its philosophical issues overlap with the fields of metaphysics or epistemology.
Political philosophy is a branch of philosophy that aims to seek knowledge on the essence of politics.
It examines the basic concepts,
Assumptions,
And arguments in the field of politics.
It investigates the nature and purpose of government and compares its different forms.
It further asks under what circumstances the use of political power is legitimate,
Rather than a form of simple violence.
In this regard,
It is concerned with the distribution of political power,
Social and material goods,
And legal rights.
Other topics are justice,
Liberty,
Equality,
Sovereignty,
And nationalism.
Political philosophy involves a general inquiry into normative matters,
And differs in this respect from political science,
Which aims to provide empirical descriptions of actually existing states.
Political philosophy is often treated as a subfield of ethics.
Influential schools of thought and political philosophy are liberalism,
Conservatism,
Socialism,
And anarchism.
Methods of philosophy are ways of conducting philosophical inquiry.
They include techniques for arriving at philosophical knowledge and justifying philosophical claims as well as principles used for choosing between competing theories.
A great variety of methods have been employed throughout the history of philosophy.
Many of them differ significantly from the methods used in the natural sciences in that they do not use experimental data obtained through measuring equipment.
The choice of one's method usually has important implications,
Both for how philosophical theories are constructed,
And for the arguments cited for or against them.
This choice is often guided by epistemological considerations about what constitutes philosophical evidence.
Methodological disagreements can cause conflicts among philosophical theories or about the answers to philosophical questions.
The discovery of new methods has often had important consequences,
Both for how philosophers conduct their research and for what claims they defend.
Some philosophers engage in most of their theorizing using one particular method,
While others employ a wider range of methods,
Based on which one fits the specific problem investigated best.
Philosophical inquiry is relevant to many fields that are connected with what to believe and how to arrive at evidence for one's beliefs.
This is a key issue for the sciences,
Which have as one of their prime objectives the creation of scientific knowledge.
Scientific knowledge is based on empirical evidence,
But it is often not clear whether empirical observations are neutral or already include theoretical assumptions.
A closely connected problem is whether the available evidence is sufficient to decide between competing theories.
Epistemological problems in relation to the law include what counts as evidence and how much evidence is required to find a person guilty of a crime.
A related issue in journalism is how to ensure truth and objectivity when reporting on events.
In the field of politics,
Philosophy addresses issues such as how to assess whether a government policy is just.
Philosophical ideas have prepared and shaped various political developments.
The idea that philosophy is useful for many aspects of life,
And society is sometimes rejected.
According to some academics,
Philosophy is mainly undertaken for its own sake,
And does not make significant contributions to existing practices or external goals.
