"Over the years the political establishment has frowned if a mainstream politician mentions marriage."
"A successful marriage requires falling in love many times, always with the same person."Iain Duncan Smith on Mignon McLaughlin
"By all means, marry. If you get a good wife, you'll become happy if you get a bad one, you'll become a philosopher."Iain Duncan Smith on Socrates
"It is not a lack of love, but a lack of friendship that makes unhappy marriages."Iain Duncan Smith on Friedrich Nietzsche
"How can a woman be expected to be happy with a man who insists on treating her as if she were a perfectly normal human being."Iain Duncan Smith on Oscar Wilde
"Don't marry the person you think you can live with marry only the individual you think you can't live without."Iain Duncan Smith on James C. Dobson
"My view is pensioners don't have the one option that people of working age have. They can't really increase their income, because they are no longer able to work."
"Work is transformative. It gives you a greater chance of a greater income. You can affect your life while you're of working age, so you have scope and opportunity. Pensioners do not."
"For families across the UK who are income-poor, but more than that, whose lives are blighted by worklessness, educational failure, family breakdown, problem debt and poor health, as well as other problems, giving them an extra pound - say through increased benefits - will not address the reason they find themselves in difficulty in the first place."
"The future of Conservatism lies in our beliefs and values, not by throwing them away. We need to shed associations that bind us to past failures, but hold faith with those things that make us Conservatives."
"When families are strong and stable, so are children - showing higher levels of wellbeing and more positive outcomes. But when things go wrong - either through family breakdown or a damaged parental relationship - the impact on a child's later life can be devastating."
