In his recent book, Is Water H2O?, Hasok Chang presents a detailed analysis of scientific
realism and enunciates a new concept of it, which he names “active scientific realism”. It is a
view of scientific realism that accentuates experimental activity for learning about reality
rather than armchair philosophy in the search for utmost metaphysical truth. Chang puts it
in a nutshell as follows: “If the buzzword for standard realism is truth, it is progress for active
realism.” (Chang 2012, 223)
This term paper attempts to critically look at this new concept, put it in the perspective of
other realist concepts and find answers to questions like the following:
• How does Chang’s concept fit into the existing landscape of scientific realism?
• What are the roots of the concept?
• What is new and attractive in it?
• What are the weaknesses of the concept?
First I’ll try to define scientific realism as a metaphysical and epistemological position as
opposed to anti-realism. In the next chapter I’ll present the main arguments for and against
scientific realism, the “no miracle” argument and the “pessimistic meta induction”, and also
look at them from Hasok Chang’s angle of view.
Then a brief overview of common realist positions in philosophy of science will be given,
including Hasok Chang’s new conception. In the following chapter I’ll try to look critically at
some aspects of Chang’s “Active Scientific Realism” and balance the strengths and
weaknesses of the concept.

Objectives and Topics
This paper examines Hasok Chang's concept of "active scientific realism" by placing it within the broader discourse of scientific realism and evaluating its theoretical foundations and practical implications for scientific inquiry.
- Analysis of traditional scientific realism and its core arguments (no-miracle, pessimistic meta-induction).
- Categorization of diverse realist positions, including structural, conjectural, and experimental realism.
- Critical exploration of the shift from a truth-oriented philosophy to an ability-oriented "active" realism.
- Evaluation of the methodological vs. epistemological nature of Chang's contribution.
Excerpt from the Book
Active Scientific Realism (Hasok Chang)
As already mentioned, Hasok Chang introduces a new conception of scientific realism, which he designates “active scientific realism”. His basic idea is “to orient the whole discourse on realism away from disputes about truth, and turn it toward the idea of reality” (Chang 2012, 217). Science should feel committed to expose theories to reality rather than engaging in metaphysical discussions about objective truth. In this sense, realism is not far from empiricism, but while empiricism is often seen as limiting our sources of knowledge to experience, active scientific realism encourages scientists to “seek out contact with reality as much as possible, and in such ways as to maximize our learning” (ibid.).
Chang starts his considerations with the suggestion of “a fundamental re-orientation in our conception of knowledge, to think of it in terms of ability rather than belief” (Chang 2012, S. 215). His intention is not to criticize traditional epistemological knowledge or definitions, but rather to show that “we can gain new and better insights by thinking of knowledge not as consisting in belief but in ability – an ability to do certain things reliably as intended, without being foiled by resistance from reality” (ibid.). Resistance or cooperation by reality is of course meant metaphorically, in the sense of a gift from nature, which teaches us knowledge by its way of reacting to our efforts in discovering its phenomena.
Summary of Chapters
Introduction: Outlines the goal of analyzing Chang's "active scientific realism" and situating it within the philosophy of science.
Definition of Scientific Realism: Provides a foundational overview of scientific realism, instrumentalism, and anti-realism, including specific philosophical commitments.
Arguments pro and contra Scientific Realism: Examines the “no miracle” argument for realism and the “pessimistic meta-induction” that challenges the truth-conveying nature of past theories.
The Bandwidth of Scientific Realism: Details various realist frameworks including Popper's conjectural, Worrall's structural, and Hacking's experimental realism.
Critique of Chang’s Active Scientific Realism: Evaluates the implications of Chang's approach, questioning whether it constitutes an epistemological advancement or a methodological tool.
Conclusion: Synthesizes the critique and reflects on whether Chang's "active" paradigm might succeed as a standard model for scientific realism.
Bibliography: Lists the cited references and suggestions for further reading regarding the philosophy of science and realism.

Frequently Asked Questions
What is the core focus of this research paper?
The paper focuses on Hasok Chang's concept of "active scientific realism," which redefines scientific realism by shifting the focus from the attainment of absolute truth to the development of practical abilities and engagement with reality.
What are the primary themes discussed in the work?
The paper addresses the definition of realism, historical and modern arguments like the "no miracle" argument, the spectrum of existing realist positions, and the move toward pluralism and activity in scientific endeavors.
What is the primary goal of the author?
The primary goal is to critically evaluate Chang's new concept, place it within the context of existing realist paradigms, and determine if it represents a significant shift in how we understand scientific knowledge.
Which scientific method is utilized in this paper?
The paper employs a comparative and critical literature review, analyzing Chang's work alongside that of prominent philosophers such as Hacking, Popper, and Worrall.
What content is covered in the main body?
The main body covers the theoretical pillars of traditional realism, the bandwidth of different realist flavors, and a specific critique of Chang’s arguments regarding epistemic humility versus confidence.
Which keywords characterize this study?
The study is best characterized by terms like Active Scientific Realism, Epistemology, Scientific Practice, Scientific Pluralism, and the debate between truth-oriented versus ability-oriented knowledge.
How does Chang differentiate his concept from "Standard Scientific Realism"?
Chang critiques "Standard Scientific Realism" for its fixation on "truth," proposing instead that science should be evaluated by its "progress" and its ability to engage with reality through active experimentation.
What is the significance of the "pessimistic meta-induction" in the paper?
The paper uses this argument to show that because many past successful theories were ultimately abandoned, we cannot simply equate the success of a theory with its absolute truth.
How does the author view the debate between "humility" and "confidence"?
The author analyzes Chang's call for epistemic humility as a necessary safeguard against the hubris of believing we have attained a complete and final objective truth.
Is Chang's approach considered an epistemological or methodological concept?
The paper debates this, concluding that while it touches on epistemology, it functions primarily as a methodological recipe for organizing and conducting scientific inquiry.
