Posters are going up in buses in Manchester, Liverpool, and Birmingham today as part of 'Thought for the Commute', a new month-long campaign by the British Humanist Association (BHA).
Launching the campaign, BHA Chief Executive Andrew Copson said: "Despite over half the population in the UK describing themselves as non-religious, humanist perspectives on life's big questions are still far less available to the public than religious ones.
"In our state schools, religions are taught about but non-religious worldviews like Humanism are seldom given the same treatment.
"In our state media, the BBC, sermons and prayers are broadcast but rarely contain any content engaging with questions of value and meaning from a humanist point of view. As a result, many people whose beliefs are essentially humanist are unaware of the fact.
The posters will encourage commuters to think about meaning in life under the question 'What's it all for?', presenting views from four famous humanists: physicist Jim Al-Khalili, Indian statesman Jawarharlal Nehru, philosopher Bertrand Russell and writer and comedian Natalie Haynes.
Running alongside the posters will be a 'rush hour' social media campaign featuring a wider range of thoughts from humanist writers, as well as quizzes encouraging people to think about life.
Commuters will also be encouraged to tweet their own answers to the question along with selfies with their favourite posters.
'Thought for the Commute' follows the BHA's London Tube campaign and 'That's Humanism' video series starring Stephen Fry that launched earlier this year.
