Everyone has the right to an opinion. Everyone has the right to consider the big questions of their life and to make up their own mind about what they think. Today there are lots of very important questions that each one of us needs to think about. We need to think through questions like: What do you believe are the causes of famine in the world, or what is the reason why countries go to war or whether all pupils should be made to wear school uniforms. All of us can make a contribution to the big questions of our time. But, first of all, we need to work out what we think ourselves about these big questions.
