Human Nature, Science, and Free Will
Hypothetico-Deductive Method
The process begins with identifying a problematic situation. A hypothesis, or possible explanation, is then formulated. Using deductive reasoning, the consequences of this hypothesis are explored. These consequences are then tested through observation and experimentation. A sufficient number of carefully selected cases allows for verification or refutation of the hypothesis. If the expected consequences are not met, the hypothesis is rejected, and a new one is formulated. If the consequences align with expectations, the hypothesis is confirmed, potentially leading to a new law or theory.
Progress and Limits of Science
Scientism, the belief that science is the ultimate achievement of human rationality, often treats scientific principles as unquestionable dogmas rather than provisional truths. Two contrasting perspectives are relevant:
Popper’s Falsificationism: Popper argued that no theory can be considered definitively true because it could be falsified in the future. Science progresses as new theories, closer to the truth, replace falsified ones.
Kuhn’s Paradigm Shifts: Kuhn challenged Popper’s view, arguing that the history of science reveals that theories are not always immediately abandoned when falsified. Anomalies within a paradigm are often tolerated until a new paradigm emerges.
Dualism
Dualism distinguishes between body and mind.
Plato’s Dualism: Plato believed humans are composed of an immortal soul and a mortal body, which imprisons the soul. The soul’s natural state is separate from the body.
Descartes’ Dualism: Descartes viewed the human being as composed of mind and body. The mind is characterized by thought, while the body is characterized by extension and subject to physical laws.
Monism
Monism posits that the human being is a unitary entity, denying the mind’s existence as separate from the brain.
- Spiritualism: This perspective questions the brain’s independence from the mind.
- Materialism: This view asserts that humans are fundamentally physical, and the mind is not fundamentally different from physical phenomena. Conductism, a form of materialism, ignores the mind and focuses on observable behavior. Identity theory equates mental states with neurophysiological states.
Determinism
Determinism argues that everything is caused. The principle of causality states that every event is caused by another. All events are part of a chain of cause and effect. Human actions are also determined by factors beyond our control.
Indeterminism
Indeterminism challenges determinism, arguing that actions are not solely determined by external factors but also by conscious agency.
Responsibility
Responsibility involves taking ownership of our actions.
Responsibility from a Deterministic Perspective: If everything is determined, there is no room for free will, and therefore, no responsibility.
Responsibility from an Indeterministic Perspective: Because actions are the result of conscious agency, we are responsible for them.
