- IDEA 1 OF 8
Everyone already philosophises
Blackburn argues that philosophy is not a remote subject but something everyone does when they wonder about knowledge, mind, morality or God.
His book introduces these big questions in clear language and invites readers to think them through.
- IDEA 2 OF 8
Can we know anything?
Blackburn begins with Descartes and sceptical arguments that we might be dreaming or deceived.
He explains how philosophers have tried to answer these doubts and why the questions are harder than they look.
- IDEA 3 OF 8
How do minds fit with bodies?
Blackburn explores the puzzle of how thoughts and feelings relate to the physical brain.
He considers dualism, which separates mind and body, and alternatives that see the mind as part of the physical world.
- IDEA 4 OF 8
Are we truly free?
Blackburn discusses whether our choices are free if everything has causes.
He explains different views on free will and responsibility. Some argue freedom fits with causes, while others insist it cannot.
- IDEA 5 OF 8
What is the self?
Blackburn asks what makes a person the same over time.
He considers memory, body and psychological continuity. Puzzle cases, like perfect copies of a person, test our ordinary intuitions about identity.
- IDEA 6 OF 8
Arguments about God
Blackburn examines classic arguments for God's existence, such as design and first cause.
He explains their strengths and weaknesses. He treats each argument fairly, leaving readers to weigh the evidence.
- IDEA 7 OF 8
Reasoning needs care
Blackburn introduces logic and good reasoning, showing how arguments work and how they can go wrong.
Careful thinking helps avoid confusion. Spotting bad arguments is a skill that helps in every part of life.
- IDEA 8 OF 8
The world has puzzles
Blackburn discusses questions about causation, laws of nature and induction.
He shows how philosophy helps us understand the structure of the world. Even ordinary ideas like cause and law turn out to be surprisingly deep.
