1.1 Defining philosophy of biology and its scope

Philosophy of biology explores the foundations of biological concepts and theories. It analyzes key ideas like evolution, species, and function, while examining the nature of biological explanations and their relationship to other sciences.

This field bridges philosophy and biology, clarifying concepts and scrutinizing assumptions. It tackles ethical issues in biological research and applications, informing public policy on topics like genetic engineering and conservation.

1 of 3

• Provide a conceptual analysis of the foundational concepts, methods, and theories in biology
• Examine the nature of biological explanations (reductionism vs. holism)
• Analyze the structure of evolutionary theory (scientific theory or metaphysical framework)
• Investigate the concept of biological function (objective features or observer-attributed)

Clarification and Critical Examination of Philosophical Assumptions and Implications

• Clarify and critically examine the philosophical assumptions and implications underlying biological research and theorizing
• Scrutinize the assumptions and methods of biological research to uncover hidden biases, limitations, and potential pitfalls
• Encourage scientists to think critically about the foundations and implications of their work, stimulating new research directions and hypotheses

Epistemological and Metaphysical Foundations of Biology

• Investigate the epistemological and metaphysical foundations of biology
• Explore questions about the nature of biological knowledge (empiricism, realism, constructivism)
• Examine the reality of biological entities (species, genes, ecosystems)
• Analyze the relationship between biology and other sciences (autonomy vs. reduction)

Ethical and Social Dimensions of Biological Research and Applications

• Explore the ethical and social dimensions of biological research and its applications
• Address issues related to genetic engineering (cloning, gene editing), conservation biology (biodiversity, sustainability), and the use of animals in research (animal welfare, ethics)
• Inform public policy and decision-making regarding issues such as genetic privacy, environmental conservation, and the regulation of biotechnology

Key Questions in Philosophy of Biology

Nature of Biological Explanations

• What constitutes a satisfactory explanation in biology?
• Are biological explanations reducible to physical or chemical explanations? (reductionism vs. holism)
• How do biological explanations differ from explanations in other sciences? (mechanistic, functional, evolutionary explanations)
• What is the role of teleology and function in biological explanations? (purpose, design, adaptation)

Structure and Status of Evolutionary Theory

• Is evolution by natural selection a scientific theory or a metaphysical framework?
• What is the nature of the evidence supporting evolutionary theory? (fossil record, comparative anatomy, molecular biology)
• How does evolutionary theory relate to other biological theories? (genetics, ecology, developmental biology)
• What are the limitations and criticisms of evolutionary theory? (adaptationism, gradualism, species selection)

Concept of Biological Function

• How should we understand the notion of function in biology?
• Are functions objective features of biological systems or are they attributed by observers? (realism vs. conventionalism)
• What is the relationship between function and selection? (selected effects, causal role, goal-directedness)
• How do different concepts of function apply to different levels of biological organization? (molecular, cellular, organismal, ecological)

Nature of Species and Other Biological Categories

• Are species real entities or convenient constructs? (realism vs. nominalism)
• How should we define and delimit species boundaries? (biological species concept, phylogenetic species concept, ecological species concept)
• What is the ontological status of higher taxa (genera, families, orders) and other biological categories? (natural kinds, individuals, classes)
• How do different species concepts affect biological practice and theory? (classification, conservation, speciation)

Philosophy of Biology vs Other Fields

Philosophy of Biology as a Subfield of Philosophy of Science

• Philosophy of biology is a subfield of philosophy of science that focuses specifically on conceptual and foundational issues in biology
• General philosophy of science addresses broader questions about the nature of scientific knowledge and practice across all scientific disciplines (demarcation, confirmation, explanation)
• Philosophy of biology draws on tools and concepts from general philosophy of science but applies them to the specific context of biological research and theorizing

Distinction between Philosophy of Biology and Biology

• Philosophy of biology is concerned with the philosophical analysis of biological concepts, theories, and methods
• Biology itself is the empirical study of living organisms and their processes (anatomy, physiology, ecology, evolution)
• Philosophers of biology engage in conceptual and theoretical analysis, drawing on tools from logic, epistemology, and metaphysics
• Biologists primarily conduct empirical research using experimental and observational methods (field studies, laboratory experiments, mathematical modeling)

Relevance of Philosophy in Biology

Clarification and Precision of Biological Concepts

• Philosophical analysis can help clarify and precisify key biological concepts, such as species, gene, and fitness
• Conceptual clarification leads to more rigorous and coherent theoretical frameworks in biology
• Examples: the biological species concept, the molecular gene concept, the propensity interpretation of fitness

Improvement of Scientific Practice through Philosophical Scrutiny

• Philosophical scrutiny of the assumptions and methods of biological research can uncover hidden biases, limitations, and potential pitfalls
• Identifying and addressing these issues contributes to the improvement of scientific practice in biology
• Examples: critiques of adaptationism, the units of selection debate, the role of idealization in biological models

Stimulation of New Research Directions and Hypotheses

• Engaging with philosophical questions can stimulate new research directions and hypotheses in biology
• Philosophical reflection encourages scientists to think critically about the foundations and implications of their work
• Examples: the development of evolutionary developmental biology (evo-devo), the incorporation of niche construction into evolutionary theory

Informing Public Policy and Decision-Making

• Philosophical reflection on the ethical and social dimensions of biological research can inform public policy and decision-making
• Philosophers of biology contribute to discussions on issues such as genetic privacy, environmental conservation, and the regulation of biotechnology
• Examples: the ethical implications of gene editing (CRISPR), the value of biodiversity, the precautionary principle in environmental policy
