Quote by Bertrand Russell
It is clear that thought is not free if the profession of certain opinions makes it impossible to earn a living.
Summary
This quote highlights the restriction of freedom of thought when expressing certain opinions becomes a barrier to making a livelihood. It implies that when individuals are penalized and face consequences, such as losing employment opportunities or facing financial hardship, for expressing non-conventional or unpopular ideas, the supposed freedom of thought is compromised. It emphasizes the importance of a society that allows for open expression of opinions, without fear of detrimental consequences, in order to truly uphold the notion of freedom of thought.
