An elderly German gentleman is shuffling round the British Library. It is 1867 and he has just published the first part of Das Kapital. Looking at his grey beard and shabby suit, you would not guess that his book was about to change history.
The man was Karl MarxA 19th-Century German economist and philosopher who argued that capitalism was doomed to collapse. and his political theories went on to dominate 20th Century politics. But most big ideas - from human rights to Einstein's theory of relativityGeneral relativity is the basic idea that instead of an invisible force that attracts objects to one another, gravity is a warping of space. The more massive the object, the more it warps the space around it. - have started in the same small way, with a lone individual in a library or laboratory.

This list suggests that ideas can change history.

No: Ideas can be interesting and even influential, but the wars and elections taking place across the world in 2024 will be much more important than the ideas of any single thinker.
Or... The policies and theories used by politicians and activists must come from somewhere, and by studying new ideas we can make informed guesses about which direction our society is moving.
