2 What Philosophy Is by Yoni Porat

What is philosophy?

By Yoni Porat

Many answers have been offered in reply to this question and most are angling at something similar. One answer is that philosophy is that it is the love of wisdom (Philo = love, Sophos = Wisdom).

Perhaps you think science exhausts inquiry. About a hundred years ago, many philosophers, especially the Logical Positivists, thought there was nothing we could intelligibly inquire into except for scientific matters. But this view is probably not right. What branch of science addresses the question of whether or not science covers all of rational inquiry? If the question strikes you as puzzling, this might be because you already recognize that whether or not science can answer every question is not itself a scientific issue. Questions about the limits of human inquiry and knowledge are philosophical questions.

We can get a better understanding of philosophy by considering what sorts of things other than scientific issues humans might inquire into. Philosophical issues are as diverse and far ranging as those we find in the sciences, but a great many of them fall into one of four big topic areas: metaphysics, epistemology, logic, and ethics.

Metaphysics

Metaphysical issues are concerned with the nature of reality. Traditional metaphysical issues include the existence of God and the nature of human free will (assuming we have any). Here are a few metaphysical questions of interest to contemporary philosophers: What is it that makes a thing a thing? How are space and time related? Does the past exist? How about the future? How many dimensions does the world have? Are there any entities beyond physical objects (like numbers, properties, and relations)? If so, how are they related to physical objects? Historically, many philosophers have proposed and defended specific metaphysical positions, often as part of systematic and comprehensive metaphysical views. But attempts to establish systematic metaphysical world views have been notoriously unsuccessful.

Since the 19th century many philosophers and scientists have been understandably suspicious of metaphysics, and it has frequently been dismissed as a waste of time, or worse, as meaningless. But in just the past few decades metaphysics has returned to vitality. As difficult as they are to resolve, metaphysical issues are also difficult to ignore for long. Contemporary analytic metaphysics is typically taken to have more modest aims than definitively settling on the final and complete truth about the underlying nature of reality. A better way to understand metaphysics as it is currently practiced is as aiming at better understanding how various claims about reality logically hang together or conflict. Metaphysicians analyze metaphysical puzzles and problems with the goal of better understanding how things could or could not be. Metaphysicians are in the business of exploring the realm of possibility and necessity. They are explorers of conceptual space.

Epistemology

Epistemology is concerned with the nature of knowledge and justified belief. What is knowledge? Can we have any knowledge at all? Can we have knowledge about the laws of nature, the laws or morality, or the existence of other minds? The view that we can’t have knowledge is called skepticism. An extreme form of skepticism denies that we can have any knowledge whatsoever. But we might grant that we can have knowledge about some things and remain skeptics concerning other issues. Many people, for instance, are not skeptics about scientific knowledge, but are skeptics when it comes to knowledge of morality. Some critical attention reveals that scientific knowledge and moral knowledge face many of the same skeptical challenges and share some similar resources in addressing those challenges. Many of the popular reasons for being more skeptical about morality than science turn on philosophical confusions.

Even if we lack absolute and certain knowledge of many things, our beliefs about those things might yet be more or less reasonable or more or less likely to be true given the limited evidence we have. Epistemology is also concerned with what it is for a belief to be rationally justified.

Even if we can’t have certain knowledge of anything (or much), questions about what we ought to believe remain relevant.

Logic

Logic is the study of arguments. Informal logic involves looking at different types of arguments and distinguishing the good from the bad. Formal logic looks at arguments solely in terms of their form. It is a type of mathematics on language, where the only values are true or false, 0 or 1. It can be used to evaluate whether the argument is logically perfect and also what conclusions can be drawn from it with absolute confidence.

Ethics

While epistemology is concerned with what we ought to believe and how we ought to reason, Ethics is concerned with what we ought to do, how we ought to live, and how we ought to organize our communities. Sadly, it comes as a surprise to many new philosophy students that you can reason about such things. Religiously inspired views about morality often take right and wrong to be simply a matter of what is commanded by a divine being or beings. Cultural Relativism, perhaps the most popular opinion among people who have rejected faith, simply substitutes the commands of society for the commands of God or gods. Commands are simply to be obeyed, they are not to be inquired into, assessed for reasonableness, or tested against the evidence. Thinking of morality in terms of whose commands are authoritative leaves no room for rational inquiry into how we ought to live, how we ought to treat others, or how we ought to structure our communities. Philosophy, on the other hand, takes seriously the possibility of rational inquiry into these matters. If philosophy has not succeeded in coming up with absolutely certain and definitive answer in ethics, this is in part because philosophers take the answers to moral questions to be things we need to discover, not simply matters of somebody’s say so. The long and difficult history of science should give us some humble recognition of how difficult and frustrating careful inquiry and investigation can be. So we don’t know for certain what the laws of morality are. We also don’t have a unified field theory in physics. Why expect morality to be any easier?

We might think of metaphysics as concerned with “What is it?” questions, epistemology as concerned with “How do we know?” questions, and ethics as concerned with “What should we do about it?” questions. Many interesting lines of inquiry cut across these four kinds of questions. The philosophy of science, for instance, is concerned with metaphysical issues about what science is, but also with both epistemological questions about how we can know scientific truths and logical questions about what has to be true. The philosophy of love is similarly concerned with metaphysical questions about what love is.

But it also concerned with questions about the value of love that are more ethical in character.

Assorted tangled vines of inquiry branch off from the four major trunks of philosophy, intermingle between them, and ultimately with other types of knowledge as well. The notion that some branches of human inquiry can proceed entirely independent of others ultimately becomes difficult to sustain.

What is the value of philosophy?

Philosophy is a branch of human inquiry and as such it aims at knowledge and understanding. We might expect that the value of philosophy lies in the value of the ends that it seeks, the knowledge and understanding it reveals. But philosophy is rather notorious for failing to establish definitive knowledge on the matters it investigates. I’m not so sure this reputation is well deserved. We do learn much from doing philosophy. Philosophy often clearly reveals why some initially attractive answers to big philosophical questions are deeply problematic, for instance. Granted, philosophy often frustrates our craving for straightforward convictions. In our first reading, Bertrand Russell argues that there is great value in doing philosophy precisely because it frustrates our desire for quick and easy answers. In denying us easy answers to big questions and undermining complacent convictions, philosophy liberates us from narrow minded conventional thinking and opens our minds to new possibilities. Philosophy often provides an antidote to prejudice not by settling big questions, but by revealing just how hard it is to settle those questions. It can lead us to question our comfortably complacent conventional opinions.
