The Problem of Induction

Inductive reasoning goes from the particular to the general, from the observed to the unobserved.

Practical Problems

• How many observations are enough?
• Even well-confirmed hypotheses can later turn out to be wrong.
• Most scientists believe they really are discovering the fundamental laws of the universe, yet we have observed only a minute fraction of the universe.

Theoretical Problem

Science is supposed to be an empirical discipline that makes no claims beyond what is observed. However, this would stop any hypothesis from going from the particular to the general.

Key Thinkers and Scientific Method

Karl Popper (1902-94)

Rejected theories that tried to explain everything.

Alfred Adler (1870-1937)

Believed that human beings are dominated... Continue reading "The Problem of Induction in Science" »

What Are Values?

Values define what is worthwhile, beneficial, important, useful, and desirable for people. They influence feelings, attitudes, and behaviors. Values encompass various types, including economical, aesthetical, and moral/ethical values.

Values and Facts

Ethical questions are challenging because value judgments (e.g., good, bad, beautiful, fair) cannot be proven true or false. While facts like "grass is green" or "the earth is round" are provable, concepts like the morality of racism or murder are not.

Different Conceptions of Ethics

1. Situational Ethics

In situational ethics, right and wrong depend on the specific situation. There are no universal moral rules or rights; each case is unique. This approach emphasizes flexible guidelines... Continue reading "Understanding Ethical Values and Frameworks" »

Metaphysics: An Introduction

The term *metaphysics* was coined by students of Aristotle. The literal meaning was "after the physics." Metaphysics is the branch of philosophy that addresses basic questions about the nature of reality.

Determinism and Freedom

According to determinism, everything that happens is determined by prior causes. The state of the universe at any moment could not be otherwise. One implication of this view is that all future states of the universe are, in principle at least, completely predictable. The principle that every event is caused is known as the *causal principle*. It is presupposed in science in everyday life. Most of the astonishing progress that science has made over the past four centuries has been made on the...
