Review Questions

• How does Bas C. van Fraassen's constructive empiricism challenge traditional views of scientific realism?
  • Van Fraassen's constructive empiricism presents a challenge to scientific realism by arguing that the aim of science is not to find true descriptions of unobservable phenomena but to develop theories that are empirically adequate. This means theories should accurately describe observable experiences rather than claiming truth about what lies beyond observation. His position suggests that success in science does not guarantee truth, which fundamentally shifts how we interpret scientific progress and understanding.
• Evaluate van Fraassen's critique of the no-miracles argument and its implications for our understanding of scientific success.
  • Van Fraassen critiques the no-miracles argument by suggesting that the success of scientific theories does not necessitate their truth. Instead, he posits that this success can be understood through other factors, such as the practical effectiveness of theories in explaining and predicting phenomena. This critique has important implications for how we understand scientific achievement, as it leads to questioning whether science's effectiveness is indicative of an accurate portrayal of reality or simply a reflection of its utility.
• In what ways does van Fraassen's perspective on empirical adequacy influence modern debates in the philosophy of science?
  • Van Fraassen's emphasis on empirical adequacy influences modern debates by shifting focus from seeking ultimate truths about unobservable entities to prioritizing how well theories fit with observable data. This perspective encourages discussions around the role of models in science and how they serve practical purposes in various fields. It also fosters a re-evaluation of what constitutes scientific success and challenges scholars to consider alternative frameworks for understanding knowledge in science beyond traditional realism.
