James Reason


Why Reason is Un-Reasonable

July 22, 2025 by Prof. Robert Long 4 Comments

The legacy of the work of James Reason does not drive much sense-able thinking in safety.

Whilst this model (yes, models matter) projects a logical linear understanding of risk and … [Read more...] about Why Reason is Un-Reasonable

Ditch the Swiss-Cheese if You Want to Understand Causality

March 17, 2024 by Prof. Robert Long Leave a Comment

Just have a read of this article for a few minutes and you will see a problem. First of these 12 ‘principles’ states ‘human error is not a moral issue’, really? Then the … [Read more...] about What is Violated in Violence?

A Critique of Pure Reason

October 12, 2016 by Prof. Robert Long 47 Comments

A Critique of Pure Reason - (With Apologies to Immanuel Kant) There is not a week goes by without someone suggesting I should read James Reason or that I haven’t read James Reason. I am also advised that I don’t read James Reason properly because somehow all worldviews must be in agreement, … [Read more...] about A Critique of Pure Reason
