What the chapter is about
Haldane explains what it means to think scientifically. A scientific mind does not accept a claim because it is old, popular or loudly said. It asks for evidence, tests ideas, and is ready to change its mind when facts prove it wrong.
The essay also warns against superstition and blind belief. Science is not only machines and laboratories; it is a way of thinking — honest, curious and patient. Students should question, observe and reason instead of merely memorising answers.
What you should learn
Think scientifically: ask for evidence, test ideas, and change your mind when facts demand it.
Key Terms
- Evidence — Facts that support or disprove an idea.
- Superstition — Belief without reason or proof.
- Hypothesis — An idea offered for testing.

- Science is a way of thinking, not only machines.
- A scientific mind asks for evidence before believing.
- Ideas must be tested, not merely accepted.
- A scientist changes his mind when facts prove him wrong.
- Superstition grows where questioning stops.

Questions with Answers
- What does Haldane mean by the scientific point of view?
It means judging ideas by evidence and testing, not by tradition, popularity or loud assertion. It is an honest habit of mind. - Why must a scientific thinker be ready to change his mind?
Because new facts may disprove an old idea. Holding on to a wrong idea out of pride blocks the growth of knowledge. - How does science differ from superstition?
Superstition believes without proof and fears questioning. Science welcomes questions and accepts only what evidence supports. - Is science only about laboratories and machines?
No. Machines are products of science, but science itself is a method of thinking — observe, question, test and reason. - What is the lesson for students?
Do not memorise blindly. Ask why, look for evidence, test ideas, and keep an open, honest mind.
