People want the right to die at a time of their own choosing. Too many families have watched helplessly as a relative dies slowly, longing for death.

There is all the difference in the world between teaching children about religion and handing them over to be taught by the religious.

But how odd that in this heathen nation of empty pews, where churches' bare, ruined choirs are converted into luxury loft living, a Labour government - yes, a Labour government - is deliberately creating a huge expansion of faith schools.

Could a government dare to set out with happiness as its goal? Now that there are accepted scientific proofs, it would be easy to audit the progress of national happiness annually, just as we monitor money and GDP.

It is now possible to quantify people's levels of happiness pretty accurately by asking them, by observation, and by measuring electrical activity in the brain, in degrees from terrible pain to sublime joy.

Inequality makes everyone unhappy, the poor most of all, and that is well within the remit of the state. More money gives less extra happiness the richer we get, yet we are addicted to earning and spending more every year.
