Karl Popper - Logic of scientific discovery

The study of phenomena through observation and experimentation Systems of theories concerned with studying the natural world through observation and experimentation

The process of reasoning from specific cases to general principles

A principle attempting to justify induction by basing it on experience, but ultimately leading to logical problems such as infinite regress

Statements concerning specific observations or experiments

Statements representing hypotheses or theories Generalizing results from the singular statements

A method of testing theories through logical comparison of conclusions, investigation of the logical form of the theory, and comparison with other theories

The process of disproving a theory by showing that its predictions are contradicted by empirical observations

The challenge of distinguishing empirical sciences from metaphysical sciences

The belief that knowledge is based on observable facts and their relationships

Utilizing empirical evidence as the basis for understanding the world

The requirement that scientific statements must be potentially falsifiable through empirical testing

Ensuring that scientific claims are grounded in observable evidence rather than unfalsifiable assertions

The distinction between the objective testability of scientific statements and the subjective beliefs or convictions of individuals

A Latin term meaning “to infinity” or “endlessly,” indicating a process that continues indefinitely. Cannot physically be tested forever is a problem, but every theory should only be capable of being tested

The process of proposing a theory, deducing specific conclusions from it, and then testing those conclusions both logically (for consistency) and empirically (for real-world reflection)

Outcomes of deductive testing where a theory can be either supported (corroborated) or disproven (falsified) based on empirical evidence

Describes the structure and function of theories within the realm of scientific inquiry

Universal statements that propose explanations or laws governing natural phenomena

The relationship between cause and effect, often explored through scientific investigation

Using redundant expressions that convey the same meaning unnecessarily In logic: Something is tautological if it is true in every possible interpretation

Discussion on interpreting the principle of causality, particularly regarding the use of “can” in defining causality. Tautological: “can” means it’s always logically possible to construct a causal explanation for any event. Synthetic: “can” suggests the world is governed by strict laws, implying that every event follows universal regularities, then the principle becomes synthetic.

Types of universal synthetic statements categorized as either strictly universal (pertaining to theories or laws - universal statements) or numerically universal (pertaining to singular statements) Strict Universality: Statements or laws that apply universally without any exceptions. Numerical Universality: Statements that apply to every instance within a specific, finite set.

Distinction between concepts or names that are universal (applicable to all instances) and those that are individual (specific to particular instances)

Differentiation between strictly existential statements, which assert the existence of specific entities or states of affairs, and their relevance to scientific inquiry
