People so often focus on the negative aspects of politics, like greed and corruption, but without politics we would be lost. It frames everything we do, and it has the power to bring about real and positive change.

Politics, Andrew Gamble reminds us, defeated slavery and secured equal rights for women and minorities. Without savvy and principled politicians and citizens willing to engage in political action, there would still be civil war in Ireland and apartheid in South Africa. Closer to home, local politicians stand up for communities and endeavour to advance the prosperity and wellbeing of their constituents.

But it hasn’t always been like this, and without good politicians we could throw it all away. Right now humanity is in a race against itself, adjusting to new technologies that are destabilizing democracy and creating massive inequalities. By thinking and acting politically, Gamble argues, we can harness the imagination and enthusiasm of people everywhere to tackle these challenges and shape a better world.
