Even so, people still find it very difficult to work out who to vote for. To make it easier, the Day has imagined how four thinkers might pick their parties this Thursday:

Hume believed in a slow reform of society, making small steps at a time.

As a firm believer in caring for other human beings, Wollstonecraft would have approved of the Lib Dems' promise to spend on social care.

Is there a right and wrong way to choose?

Yes! Voting is a serious thing. People should think carefully about who would make the best leader and who has the best ideas to change the country.

No! Your vote is your own. You can vote for whoever you think has the best fashion sense, if that is what you want to do. In democraciesCountries which have a system of government based on the idea of rule by the people., we do not say there is a "right" way to choose how to vote.
