Non Sequitur

Meaning: “It does not follow”. 

An argument whose conclusion does not follow from the premise. Examples:

“It is supported by the majority . . .

“It is a break with the past . . .

“I am an expert . . .

“It is more accessible . . .

. . . therefore it is right.”

Most fallacies can be interpreted as non sequiturs in some form. Anthony Weston, in his Rulebook for Arguments, further thought:

[Non sequitur is a] very general term for a bad argument. Try to figure out specifically what is supposed to be wrong with the argument.N104

David Fleming
Dr David Fleming (2 January 1940 – 29 November 2010) was a cultural historian and economist, based in London, England. He was among the first to reveal the possibility of peak oil's approach and invented the influential TEQs scheme, designed to address this and climate change. He was also a pioneer of post-growth economics, and a significant figure in the development of the UK Green Party, the Transition Towns movement and the New Economics Foundation, as well as a Chairman of the Soil Association. His wide-ranging independent analysis culminated in two critically acclaimed books, 'Lean Logic' and 'Surviving the Future', published posthumously in 2016. These in turn inspired the 2020 launches of both BAFTA-winning director Peter Armstrong's feature film about Fleming's perspective and legacy - 'The Sequel: What Will Follow Our Troubled Civilisation?' - and Sterling College's unique 'Surviving the Future: Conversations for Our Time' online courses.
