The Importance of Creativity and Problem Solving in Knowledge Creation
Creativity and problem-solving are essential in the process of knowledge creation. Unlike other species, humans have the ability to create explanations of the world, which has allowed them to survive and progress. Knowledge creation starts with identifying problems or conflicts between existing ideas and then generating conjectures as potential solutions. Through the process of criticism and testing, these conjectures can be refined and develop into more general theories. Progress in knowledge is achieved by continually generating new conjectures and refining existing theories.
The Fallibility of Induction and the Role of Observation
Induction, the process of inferring general statements from specific observations, has been traditionally seen as a source of knowledge. However, philosophers like Karl Popper have criticized the validity of induction. Popper argued that there is no logical basis to support induction and that observations are theory-laden. He proposed that observation plays a role in the process of testing and criticizing conjectures rather than generating them. Observation is influenced by existing theories, and theories are proposed to explain and solve problems, not derived from observations alone.
The Power of Freedom and Consent in Democracy
Democracy and the open society are built on the principles of freedom and consent. The enlightenment brought about a new kind of society where legitimacy is based on reason and identification with a fair process rather than fear and obedience. In this system, consensus is not the goal, but consent, which allows for peaceful progress and the correction of mistakes. While democracy might face challenges and the rise of hyperbole, the institutions of consent and the ability to peacefully transfer power have been remarkably successful in the anglo sphere. The recognition of human fallibility and the commitment to open-ended learning and improvement are the foundations of a functioning democracy.
The Theory of Truth and the Role of Knowledge in Popper's Philosophy
Popper's theory of truth is based on the notion of correspondence to facts. He argues that a statement is true if and only if it corresponds to the actual state of affairs. This theory of truth, which is not original to Popper, emphasizes the importance of seeking to correct errors in our knowledge. While absolute truth is unattainable, truth serves as a fundamental principle in the pursuit of knowledge and the correction of errors.
Democracy and the Role of Consensus in Popper's Philosophy
Popper challenges the traditional view that the main question in politics is who should rule. He argues that this question leads to authoritarianism and instead proposes a different question: how can we set up a system that allows for the correction of mistakes made by rulers and the replacement of leaders without resorting to violence? Popper sees democracy as the best solution to this problem, emphasizing that its value lies in its ability to remove bad policies and leaders through various systems of voting. He also counters the common misconception that consensus is crucial in democracy, arguing that democracy is about error correction rather than achieving unanimous agreement.
This episode of the Popperian Podcast features an interview that Jed Lea-Henry conducted with David Deutsch. They speak about the history of humanity and philosophy, epistemology and the problem of discovering truth, failed attempts to solve this such as with empiricism and induction, Karl Popper’s solution to this problem (conjecture and refutation), and how this animates and leads us to the Open Society.
David Deutsch is a Visiting Professor of physics at the Centre for Quantum Computation, the Clarendon Laboratory (Oxford University), an Honorary Fellow of Wolfson College (Oxford), and the author of The Fabric of Reality and The Beginning of Infinity. David works on fundamental issues in physics, particularly the quantum theory of computation and information, and constructor theory.
