The Social Contract
Members of a society should cooperate for social benefits, sacrificing some individual freedoms for state protection
People are born good but society wields a corrupting influence on them
The driving force behind society is the General Will, and it must be respected. The challenge is to attain freedom amidst corruption and worldliness.
Immanuel Kant
"Moral actions can only arise from a sense of duty (as opposed to, say, the outcome of actions, which may be pleasurable or beneficial to someone)"
Kantian Ethics – Deontology (nature of duty and obligation) – What is good arises from duty and free will
"The world of things-in-themselves is unknowable; the world of appearance, the phenomenal world governed by laws, is knowable"

The Existentialists
A leap of faith is necessary in order to define who we are; God will help us in that aspect
Human beings are unique because they can both act and be aware of it at the same time
There is no meaning to our life a priori, so the deepest striving is to define ourselves in a random and contingent world
Friedrich Nietzsche
Rejected Christianity's compassion for the weak, exalting the "will to power"
Belief in the Christian God has become unbelievable
Martin Heidegger
Dasein – Being towards death
"We're essentially alone; we come into the world alone and exit it alone"
We shouldn't be afraid of death as it is inevitable and death is merely a term for nonexistence
