We are biological creatures. We are born, we live, we die. There is no transcendent purpose to existence. At best we are creatures of reason, and by using reason we can cure ourselves of emotional excess. Purged of both hope and fear, we find courage in the face of helplessness, insignificance and uncertainty.

The twenty-first century is, and will remain, the Age of Insecurity.

We should challenge the relativism that tells us there is no right or wrong, when every instinct of our mind knows it is not so, and is a mere excuse to allow us to indulge in what we believe we can get away with. A world without values quickly becomes a world without value.

Close to a billion people - one-eighth of the world's population - still live in hunger. Each year 2 million children die through malnutrition. This is happening at a time when doctors in Britain are warning of the spread of obesity. We are eating too much while others starve.

We know – it has been measured in many experiments – that children with strong impulse control grow to be better adjusted, more dependable, achieve higher grades in school and college and have more success in their careers than others. Success depends on the ability to delay gratification, which is precisely what a consumerist culture undermines. At every stage, the emphasis is on the instant gratification of instinct. In the words of the pop group Queen, “I want it all and I want it now.” A whole culture is being infantilised.

Those who believe that liberal democracy and the free market can be defended by the force of law and regulation alone, without an internalised sense of duty and morality, are tragically mistaken.

A society in which there are high levels of voluntary activity will simply be a better, happier place than one where there are not.
