This article reviews two standard criticisms of creationism/intelligent design (ID): it is unfalsifiable, and it is refuted by the many imperfect adaptations found in nature. Problems with both criticisms are discussed. A conception of testability is described that avoids the defects in Karl Popper’s falsifiability criterion. Although ID comes in multiple forms, which call for different criticisms, it emerges that ID fails to constitute a serious alternative to evolutionary theory. 
Empiricism and Intelligent Design II: Analyzing Intelligent Design
If intelligent design (id) is to compete with evolutionary theory (et), it must meet the modified falsifiability challenge, that is, make some deductive or probabilistic observational assertions. ItExpand
Auxiliary Assumptions, Unification, and Intelligent Design: A Defense of Contrastive Testability
Boudry and Leuridan argue that in a number of cases—and specifically in the case of intelligent design—a theory can be intuitively testable, but not contrastively testable according to Sober’sExpand
On Likelihoodism and Intelligent Design
Two common and plausible claims in the philosophy of science are that (i) a theory that makes no predictions is not testable and (ii) one cannot confirm a theory by criticizing a competing one absentExpand
Where the Design Argument Goes Wrong: Auxiliary Assumptions and Unification*
Sober has reconstructed the biological design argument in the framework of likelihoodism, purporting to demonstrate that it is defective for intrinsic reasons. We argue that Sober’s restriction onExpand
Empiricism and Intelligent Design I: Three Empiricist Challenges
Due to the logical relations between theism and intelligent design (id), there are two challenges to theism that also apply to id. In the falsifiability challenge, it is charged that theism isExpand
Intelligent Design and the Nature of Science: Philosophical and Pedagogical Points
This chapter offers a critique of intelligent design arguments against evolution and a philosophical discussion of the nature of science, drawing several lessons for the teaching of evolution and forExpand
Evidence for Evolution Versus Evidence for Intelligent Design: Parallel Confusions
This clarification provides a strong criterion for showing the inability of an ID theory to be of utility in the ongoing process of acquiring causal understanding, that is the hallmark of science. Expand
The Design Argument
This Element analyzes the various forms that design arguments for the existence of God can take, but the main focus is on two such arguments. The first concerns the complex adaptive features thatExpand
Science and Illusions
It is mostly agreed that Popper's criterion of falsifiability fails to provide a useful demarcation between science and pseudo-science, because ad-hoc assumptions are always able to save any theoryExpand
Intuitions and Arguments: Cognitive Foundations of Argumentation in Natural Theology
This paper examines the cognitive foundations of natural theology: the intuitions that provide the raw materials for religious arguments, and the social context in which they are defended orExpand


Does “Intelligent Design” Have a Chance? An Essay Review
A number of authors have argued the case that there is empirical evidence that the universe (or particular configurations within it) must be the outcome of intelligent design. Recent books by WilliamExpand
No Free Lunch: Why Specified Complexity Cannot Be Purchased without Intelligence
Intelligent Design is a viewpoint in which natural processes are replaced by some kind of creation or design, in which the entire world is understood in terms of natural processes. Expand
The Application-Conditions for Design Inferences: Why the Design Arguments Need the Help of Other Arguments for God's Existence
Proponents of design arguments attempt to infer the existence of God from various properties or features of the world they take to be evidence of intelligent design. Thus, for example, theExpand
The Design Argument

The role of theology in current evolutionary reasoning
A remarkable but little studied aspect of current evolutionary theory is the use by many biologists and philosophers of theological arguments for evolution. These can be classed under two heads:Expand
Tower of Babel: The Evidence against the New Creationism
Creationism is no longer the simple notion it once was taken to be. Its new advocates have become more sophisticated in how they present their views, speaking of "intelligent design" rather thanExpand
Abusing Science: The Case Against Creationism
Abusing Science is a manual for intellectual self-defense, the most complete available for presenting the case against Creationist pseudo-science, and refutes the popular complaint that the scientific establishment is dogmatic and intolerant. Expand
Information theory, evolutionary computation, and Dembski’s “complex specified information”
Dembski asserts that CSI is present in intelligent causes and in the flagellum of Escherichia coli, and concludes that neither have natural explanations. Expand
