49:46. For Kant, morally speaking, suicide is on a par with murder. It's on a par with murder because what we violate when we take a life,
49:57: when we take someone's life, ours or somebody else's, we use that person
50:04: we use a rational being, we use humanity as a means.
50:09: And so we fail to respect humanity as an end.
50:14: And that capacity for reason, that humanity that commands respect
50:21: that is the ground of dignity
50:23: that humanity
50:25: that capacity for reason
50:28: resides undifferentiated in all of us.
50:32: And so I violate that dignity in my own person if I commit suicide and in murder.
50:39: If I take somebody else's life from a moral point of view, they're the same. And the reason they're the same, has to do with the universal character and ground of the moral law.
humanity = 2. The quality of being humane; benevolence
Question 1. Is the above definition the right one, for the noun humanity?
Question 2. Was Kant Pollyannish (see here) in his outlook on life? Does Prof Sandel mean that we all possess the same kind of humanity? Really? Even for terrorists?
