About Deontology

Deontology determines a moral framework for right and wrong — basically, rules for how to live your life. Nihilism, the philosophy that there are no moral principles and life has no meaning, can be considered the opposite of deontology. You may experience a bit of nihilism when you struggle to get out of bed to go to work. "What's the point?" you may think. Try to summon up inspiration from deontologists: Go forth and do the right thing.
