Learning outcomes
By the end of this course, students will gain foundational knowledge in analytic epistemology. They will develop key conceptual tools to critically analyze and understand complex phenomena like science denialism and the dynamics of scientific disagreement. Equipped with these conceptual tools, students will also be able to propose well-informed strategies to tackle these urgent issues, both within scientific practice and in broader societal contexts.
Course contents
After an introduction to some of the fundamental concepts and methods of analytic epistemology—such as truth, knowledge, justification, argumentative validity, testimony, and expert competence—the course will address two highly topical issues:
-
Scientific denialism, with particular attention to the case of climate change.
-
The role of agreement and disagreement in scientific practice and science communication.
More specifically, the course will focus on topics such as:
-
The definition and characteristics of scientific denialism, with specific reference to climate denialism.
-
The issue of demarcating between science and pseudoscience, and its role in understanding and contextualising scientific denialism.
-
The importance of truth and evidence in addressing science denialism and the phenomenon of post-truth.
-
The epistemological concepts of risk and uncertainty, and their significance in relation to the communication of scientific findings.
-
The role of disagreement among experts in contexts of science popularisation and science communication.
