The Nature and Scope of the Work
What Is Philosophy? (¿Qué es filosofía?) is a substantial philosophical treatise by the Spanish philosopher José Ortega y Gasset, based on a series of lectures he delivered at the University of Madrid. The work represents one of Ortega’s most systematic attempts to define the nature, method, and scope of philosophy itself, addressing fundamental questions about what distinguishes philosophical inquiry from other forms of knowledge and why philosophy matters for human existence.
The book is structured around a central paradox: philosophy claims to be the most rigorous and fundamental form of knowledge, yet it appears to be the discipline about which there is the least agreement. Unlike mathematics or physics, where practitioners share common methods and build upon established results, philosophers seem perpetually to disagree about the most basic questions—including what philosophy itself is. Ortega takes this apparent weakness as his starting point, arguing that this very characteristic reveals something essential about the philosophical enterprise.
Ortega’s approach is distinctive in that he refuses to begin with abstract definitions or to assume that philosophy can be understood apart from the concrete historical and existential circumstances in which it arises. Instead, he insists that we must understand philosophy as a human activity, something that emerges from specific needs and situations in human life. This methodological commitment reflects his broader philosophical perspective, often characterized as “perspectivism” or “vital reason” (razón vital), which holds that all knowledge is rooted in the concrete circumstances of life.
The Problem of Defining Philosophy
Ortega begins by confronting the difficulty of defining philosophy. He notes that when we ask “what is philosophy?” we are already engaged in a philosophical question, creating a kind of circularity. We cannot define philosophy from outside philosophy, yet we seem to need a definition before we can begin. This is not merely a logical puzzle but reveals something about the unique character of philosophical inquiry.
He examines various traditional definitions of philosophy—as the love of wisdom, as the science of first principles, as the study of being qua being, as the critique of knowledge—and finds each inadequate, not because they are entirely wrong but because they fail to capture what is most essential. These definitions, Ortega argues, tend to be either too narrow, excluding important aspects of what philosophy has historically been, or too vague, failing to distinguish philosophy from other intellectual pursuits.
The fundamental problem, as Ortega sees it, is that most definitions of philosophy are derived from particular philosophical systems or schools. A Platonist defines philosophy one way, an empiricist another, a Kantian yet another. Each definition presupposes a philosophical position and thus cannot serve as a neutral starting point. What we need, Ortega insists, is to identify what is common to all genuine philosophy, what makes philosophy philosophy regardless of the particular doctrines or methods employed.
Ortega proposes that we approach the question differently. Rather than seeking an abstract definition, we should ask: what is the radical problem that gives rise to philosophy? What human need or situation makes philosophy necessary? By identifying the originating problem of philosophy, we can understand its essential nature.
Philosophy as Radical Knowledge
The central thesis of Ortega’s work is that philosophy is distinguished by its radicality—it seeks to be radical knowledge, knowledge that goes to the roots (radix) of things. Philosophy is not content with partial or specialized knowledge; it demands comprehensive understanding. It asks not just “what is this particular thing?” but “what is the whole of reality?” It seeks not just to know some truths but to understand the nature of truth itself.
This radicality manifests in several ways. First, philosophy refuses to take anything for granted. While the sciences begin with certain assumptions—the physicist assumes the existence of matter and energy, the biologist assumes the existence of living organisms—philosophy questions even these fundamental assumptions. It asks: what is matter? what is existence? what is life? Philosophy, in Ortega’s view, is the discipline that accepts no presuppositions, that subjects everything to questioning.
Second, philosophy seeks autonomous knowledge—knowledge that justifies itself, that does not depend on authority or tradition or faith. The philosopher cannot simply accept what has been handed down; she must think through everything for herself, arriving at conclusions through her own rational inquiry. This demand for autonomy is what distinguishes philosophy from religion or received wisdom.
Third, philosophy aims at systematic completeness. It is not satisfied with knowing this or that; it wants to know the whole. The philosophical impulse is toward a comprehensive understanding of reality in its totality. This does not mean that philosophy must actually achieve such completeness—Ortega is well aware of the limitations of human knowledge—but that it is oriented toward this goal, that it refuses to accept fragmentation as final.
The Universe as the Fundamental Problem
Ortega argues that the fundamental problem of philosophy is the problem of the Universe—understanding reality as a whole. But what does this mean? He is careful to distinguish the philosophical concept of the Universe from the astronomical or physical concept. The Universe, in the philosophical sense, is not simply the sum total of all existing things; it is the totality of what is given to us, the comprehensive context within which we find ourselves.
This leads to one of Ortega’s most important insights: the Universe is not something we can observe from outside. We are always already within it. We cannot step back and view reality as a whole from some external vantage point. Our knowledge of the Universe must be knowledge from within, knowledge that includes ourselves as knowers. This has profound implications for how philosophy must proceed.
The Universe, as Ortega conceives it, has a peculiar structure. It is not a collection of independent objects but a relational whole in which everything is connected to everything else. Moreover, it is not static but dynamic, constantly changing and evolving. Most importantly, the Universe includes consciousness—it includes us, the beings who are trying to understand it. Any adequate philosophy must account for this fact: the Universe is such that it contains beings capable of questioning and understanding it.
This leads Ortega to reject both naive realism and subjective idealism. Naive realism treats the Universe as simply “out there,” independent of consciousness, a collection of objects that we passively observe. But this ignores the fact that our knowledge of the Universe is always mediated by consciousness, always perspectival. Subjective idealism, on the other hand, reduces the Universe to mental contents, to ideas or sensations in consciousness. But this ignores the fact that consciousness is always consciousness of something, that it is directed toward a world that transcends it.
Life as Fundamental Reality
Ortega’s solution to this dilemma is to propose that the fundamental reality is neither pure object nor pure subject but life—specifically, human life understood as the dynamic interaction between self and world. Life, in this technical sense, is not biological life but the lived experience of being in the world, the concrete situation in which each of us finds ourselves.
This concept of life has several key characteristics. First, life is always “my life”—it is radically individual and perspectival. I cannot live anyone else’s life, and no one can live mine for me. Each person’s life is a unique perspective on reality, an irreducible point of view. This does not mean that reality is subjective or arbitrary; rather, it means that reality is always given from a particular perspective, and these perspectives are not interchangeable.
Second, life is essentially temporal. It is not a static state but a continuous process of becoming. We are always projecting ourselves into the future, making decisions, choosing among possibilities. Life is fundamentally historical—it unfolds in time, and what we are at any moment depends on what we have been and what we are becoming.
Third, life is characterized by what Ortega calls “circumstance” (circunstancia). We do not choose the basic conditions of our existence—when and where we are born, our bodies, our initial social context. We find ourselves “thrown” into a particular situation. Yet within these circumstances, we must choose, we must act, we must make something of ourselves. Life is thus a combination of fate and freedom, of what is given and what we make of what is given.
Fourth, life is essentially problematic. Unlike a stone, which simply is what it is, human beings must decide what to be. We are confronted with possibilities, with choices, with the need to give meaning and direction to our existence. This is why philosophy arises: because human life is inherently questionable, because we must understand ourselves and our world in order to live.
The Method of Philosophy
Given this understanding of philosophy’s fundamental problem and its grounding in life, what method should philosophy employ? Ortega is critical of many traditional philosophical methods, which he sees as inadequate to the task.
He rejects pure rationalism, the attempt to deduce all knowledge from self-evident first principles. Such rationalism, exemplified by Descartes and the great system-builders, assumes that reason can operate independently of experience, that we can arrive at truth through pure thought. But this ignores the rootedness of all thinking in concrete life. Reason is not a disembodied faculty but an activity of living beings, and it must remain connected to the lived experience from which it arises.
At the same time, Ortega rejects pure empiricism, the reduction of knowledge to sense experience. Empiricism fails to recognize that experience is always already interpreted, always structured by concepts and meanings. We do not simply receive raw sense data; we experience a meaningful world. Moreover, empiricism cannot account for the universal and necessary truths that philosophy seeks.
Ortega proposes instead what he calls the method of “vital reason” or “historical reason.” This method begins with the concrete reality of human life and seeks to understand how meaning, truth, and value emerge from this foundation. It recognizes that human beings are historical creatures, that we are shaped by our past and oriented toward our future, and that any adequate understanding must take this temporality into account.
The method of vital reason involves several steps. First, we must describe the fundamental structures of human life—the fact that we find ourselves in a world, that we must choose and act, that we are temporal beings, that we are always in relation to others. This is a kind of phenomenological description, an attempt to articulate what is given in lived experience.
Second, we must understand how these structures give rise to the various forms of human activity—science, art, morality, politics, religion. Each of these is a way of responding to the fundamental situation of human life, a way of making sense of our existence and giving it direction.
Third, we must recognize the historical character of human existence. We are not abstract, timeless beings but creatures of a particular time and place. Our problems, our possibilities, our ways of understanding are shaped by our historical situation. Philosophy itself has a history, and we cannot understand what philosophy is without understanding how it has developed and changed.
Philosophy and the Sciences
A significant portion of Ortega’s analysis is devoted to distinguishing philosophy from the sciences. This is crucial because in the modern world, science has achieved enormous prestige and success, and there is a temptation to model philosophy on science or even to replace philosophy with science.
Ortega argues that while philosophy and science are related, they are fundamentally different enterprises. Science is specialized knowledge. Each science carves out a particular domain of reality—physics studies matter and energy, biology studies living organisms, psychology studies mental phenomena—and investigates it using specific methods. Science is content to bracket larger questions and focus on what can be precisely measured and tested.
Philosophy, by contrast, seeks comprehensive knowledge. It refuses to accept the fragmentation of knowledge into separate disciplines. It asks about the relationships among the sciences, about their foundations, about what they presuppose. While the physicist takes space and time for granted, the philosopher asks: what is space? what is time? While the biologist assumes the existence of life, the philosopher asks: what is life? what distinguishes the living from the non-living?
Moreover, science is cumulative and progressive in a way that philosophy is not. Scientific knowledge builds on previous discoveries; later scientists stand on the shoulders of earlier ones. In philosophy, by contrast, we cannot simply assume the results of previous thinkers. Each philosopher must, in a sense, begin again, must think through the fundamental questions for herself. This is not a defect of philosophy but reflects its nature as radical inquiry.
Yet Ortega insists that philosophy and science need each other. Science without philosophy becomes blind, losing sight of its larger meaning and purpose. Philosophy without science becomes empty, disconnected from concrete knowledge of the world. The ideal is a fruitful interaction in which philosophy provides the broader framework and critical reflection, while science provides detailed empirical knowledge.
The Historical Character of Philosophy
One of Ortega’s most important contributions is his insistence on the historical character of philosophy. Philosophy is not a timeless pursuit of eternal truths but a historical activity, shaped by the particular circumstances and problems of each age.
This does not mean that philosophy is merely relative or arbitrary. Ortega is not a simple relativist who believes that all philosophical positions are equally valid. Rather, he argues that each age faces particular problems and develops particular concepts and methods to address them. These are genuine advances in understanding, even if they are not final or absolute.
For example, ancient Greek philosophy arose in response to the discovery of reason and the possibility of rational inquiry. The Greeks were the first to ask: what can we know through reason alone, independent of myth and tradition? Medieval philosophy grappled with the relationship between faith and reason, between revealed truth and philosophical inquiry. Modern philosophy, beginning with Descartes, focused on the problem of certainty and the foundations of knowledge.
Each of these philosophical movements made genuine discoveries and developed important concepts. But each was also limited by its historical situation, by the problems it faced and the conceptual resources available to it. We cannot simply return to Greek philosophy or medieval philosophy as if nothing had happened since. We must build on their insights while recognizing their limitations.
Ortega’s own philosophy is shaped by the crisis of his time—the early twentieth century, with its world wars, its political upheavals, its questioning of traditional values and certainties. He sees his task as developing a philosophy adequate to this new situation, one that recognizes the historical and perspectival character of human existence while avoiding both dogmatism and nihilism.
The Relationship Between Philosophy and Life
Throughout the work, Ortega returns to the relationship between philosophy and life. Philosophy, he insists, is not an escape from life but a deepening of it. We philosophize not to flee the world but to understand it better, to live more authentically and fully.
This has important implications for how we should view philosophy. Philosophy is not a luxury, not something only for specialists or academics. It is a fundamental human need, arising from the problematic character of human existence. We all face the question of how to live, what to believe, what to value. We all need some understanding of ourselves and our world. Philosophy is the systematic pursuit of such understanding.
At the same time, Ortega recognizes that philosophy can become detached from life, can become a sterile academic exercise. This happens when philosophers forget the existential roots of their inquiry, when they pursue abstract problems for their own sake without connection to the lived experience that gives them meaning. Ortega is critical of much academic philosophy for this reason.
The authentic philosopher, in Ortega’s view, is one who remains connected to life, who philosophizes out of genuine need and perplexity. Such a philosopher does not simply repeat traditional doctrines or engage in clever logical games but grapples with real problems, seeks genuine understanding, and is willing to follow the argument wherever it leads.
Perspectivism and Truth
A crucial aspect of Ortega’s philosophy, developed in this work, is his perspectivism. This is the view that all knowledge is perspectival—it is always from a particular point of view, a particular situation in life. There is no “view from nowhere,” no God’s-eye perspective from which we can see reality as it is in itself.
This might seem to lead to relativism—the view that there is no objective truth, that all perspectives are equally valid. But Ortega rejects this conclusion. He argues that perspectives are not arbitrary or subjective but are determined by our real situation in the world. Different perspectives reveal different aspects of reality, and all are necessary for a complete understanding.
The analogy Ortega uses is visual perspective. When I look at a landscape, I see it from a particular location. Someone standing elsewhere sees a different view. Neither of us sees the landscape “as it really is” in some absolute sense; we each see it from our position. Yet our views are not arbitrary—they are determined by where we actually are. And to understand the landscape fully, we need to integrate multiple perspectives.
Similarly, in philosophy and in life generally, different individuals and different cultures have different perspectives on reality. These perspectives are shaped by historical circumstances, by social position, by individual experience. But they are not merely subjective—they reveal real aspects of reality. Truth is not the elimination of perspective but the integration of perspectives, the recognition that reality is richer and more complex than any single viewpoint can capture.
This perspectivism has important ethical and political implications. It suggests that we should be open to other perspectives, that we should recognize the partiality of our own view, that we should seek dialogue and integration rather than imposing our perspective as absolute. Yet it does not collapse into a relativism that says all views are equally good. Some perspectives are more adequate than others, some are distorted or limited. The task is to distinguish better from worse perspectives and to work toward a more comprehensive understanding.
The Future of Philosophy
Ortega concludes by reflecting on the future of philosophy. He is writing at a time of crisis—the early twentieth century, when traditional certainties were being questioned, when European civilization seemed to be in decline. What role can philosophy play in such a time?
Ortega is cautiously optimistic. He believes that philosophy has an essential role to play precisely because it is the discipline that questions foundations, that refuses to take anything for granted. In a time of crisis, when old answers no longer satisfy, we need philosophy to help us think through fundamental questions anew.
But philosophy can only fulfill this role if it remains true to its nature as radical inquiry, if it refuses to become dogmatic or to align itself uncritically with any particular ideology or system. The philosopher must be willing to question everything, including her own assumptions, and to follow the argument wherever it leads.
Ortega also emphasizes the need for philosophy to remain connected to life, to address the real problems and perplexities that people face. A philosophy that becomes too abstract, too technical, too removed from lived experience will lose its vitality and its relevance. The challenge is to maintain philosophical rigor while remaining engaged with the concrete realities of human existence.
Ortega y Gasset and His Context
José Ortega y Gasset was one of the most important Spanish philosophers of the twentieth century and a major figure in European thought more broadly. Born in Madrid, he was deeply engaged with both Spanish culture and the broader European philosophical tradition. He studied in Germany and was influenced by neo-Kantianism and phenomenology, particularly the work of Edmund Husserl, though he developed his own distinctive philosophical approach.
Ortega was not only a philosopher but also a public intellectual, deeply involved in the cultural and political life of Spain. He founded the journal Revista de Occidente, which introduced Spanish readers to contemporary European thought, and he wrote extensively on politics, culture, and society. His work reflects a concern with the “problem of Spain”—the question of Spain’s relationship to European modernity and its own cultural identity.
What Is Philosophy? represents a mature statement of Ortega’s philosophical position. It builds on ideas he had developed in earlier works but presents them in a more systematic and comprehensive form. The work reflects his engagement with the major philosophical movements of his time—phenomenology, existentialism, historicism—while developing a distinctive perspective that emphasizes the concrete reality of human life and the perspectival character of all knowledge.
The book is significant both as a contribution to metaphilosophy—reflection on the nature of philosophy itself—and as an expression of Ortega’s broader philosophical vision. It shows how his concepts of vital reason, perspectivism, and the primacy of life inform his understanding of what philosophy is and should be. For readers interested in Ortega’s thought, this work provides an essential entry point and a framework for understanding his other writings.
The influence of What Is Philosophy? extends beyond academic philosophy. Ortega’s emphasis on the historical and perspectival character of human existence, his critique of abstract rationalism, and his insistence on the connection between philosophy and life have resonated with readers concerned with the relevance of philosophy to contemporary problems. His work anticipates and contributes to later developments in hermeneutics, existentialism, and postmodern thought, while maintaining a commitment to rational inquiry and the pursuit of truth that distinguishes it from more radical forms of relativism.
