difference between prisoner's dilemma and tragedy of the commons
Prisoner's dilemma Many real-life dilemmas involve multiple players.[29] Although metaphorical, Hardin's tragedy of the commons may be viewed as an example of a multi-player generalization of the PD: Each villager makes a choice for personal gain or restraint. The collective reward for unanimous (or even frequent) defection is very low payoffs (representing the destruction of the "commons"). A commons dilemma most people can relate to is washing the dishes in a shared house. By not washing dishes an individual can gain by saving his time, but if that behavior is adopted by every resident the collective cost is no clean plates for anyone.
Redemption (theology) In Christian theology, redemption (Greek: apolutrosis) refers to the deliverance of Christians from sin.[1] It assumes an important position in salvation because the transgressions in question form part of a great system against which human power is helpless.[2] Leon Morris says that "Paul uses the concept of redemption primarily to speak of the saving significance of the death of Christ."[3] In the New Testament, the redemption word group[further explanation needed] is used to refer both to deliverance from sin and freedom from captivity.[4] In Christian theology, redemption is a metaphor for what is achieved through the Atonement;[4] therefore, there is a metaphorical sense in which the death of Jesus pays the price of a ransom, releasing Christians from bondage to sin and death.[5]
