I find it significant that, even though contemporary philosophy tends towards forms of determinism, in the wider culture people are deeply into naming, shaming and blaming each other. So we haven't lost that sense of conscience.

Peter Breggin, an American psychiatrist, had been criticising SSRIs since the early 1990s. He wrote 'Talking Back to Prozac' (1995) to repudiate psychiatrist Peter Kramer's 'Listening to Prozac' (1993) - a bestseller which claimed that Prozac made patients 'better than well.'

The issue of the environment as seen by Pope Francis is not a matter of purely scientific or, indeed, theological debate: it involves economic and political views on how the world's poor can be brought out of poverty while protecting the environment.

Pope Francis emphatically does not buy the argument that poverty can be alleviated by the 'trickle down' effects of wealth creation. He is deaf to arguments that the global economy has brought a billion people out of poverty. He is convinced, in short, that the best and only way to expel poverty is fairer distribution of the world's goods.
