Moral philosophers have been attempting to determine what makes a person inherently good or bad for thousands of years.
Each religion has its own set of rules which set out which side of the scales you will fall on.
But the whole issue has been reduced to its simplest form by one scenario, which is being shared hundreds of thousands of times on social media.
And it involved a shopping trolley, reports The Mirror.
The 'shopping trolley theory' was shared on Twitter, and it goes like this: "The shopping cart is the ultimate litmus test for whether a person is capable of self-governing.
"To return the shopping cart is an easy, convenient task and one which we all recognise is the correct, appropriate thing to do.
"To return a shopping cart is objectively right. There are no situations other than dire emergencies in which a person is not able to return their cart.
"Simultaneously, it is not illegal to abandon your shopping cart. Therefore the shopping cart presents itself as the apex example of whether a person will do what is right without being forced to do it.
"No one will punish you for not returning the shopping cart, no one will fine you or kill you for not returning the shopping cart, you gain nothing for returning the shopping cart.
"You must return the shopping cart out of the goodness of your own heart. You must return the shopping cart because it is the right thing to do. Because it is correct.
"A person who is unable to do this is no better than an animal, an absolute savage who can only be made to do what is right by threatening them with law and the force that stands behind it.
"The shopping cart is what determines whether a person is a good or bad member of society."
So are you good, or bad?
