David Hume: Why You're Probably Wrong About Everything You Know

David Hume was completely at ease with contradictions. This way he could avoid getting into extremities. 

He used to contradict himself by providing a counter-argument against his own statements. This way, no matter how contradictory it sounded, it provided an insight into life, which itself does not follow a linear, logical path.

David Hume argued that we can't always be selfish and self-centered as we are ultimately unable to live without other people.

If we do wrong to someone, the unbiased spectator in us (conscience), will see that, providing us feelings of guilt, or remorse.

Normally, philosophy teaches us new ways of thinking but rarely does it provide us with ways to live.

A true human is he who doubts yet is man enough to admit his mistakes.

A living philosophy sees the world as it is, without any color of belief or ideology.
