"Men did not make the earth ... it is the value of the improvement only, and not the earth itself, that is individual property... Every proprietor owes to the community a ground rent for the land which he holds." -- Thomas Paine, Agrarian Justice
None of the Above.
Whether a life matters depends upon the individual and what they do to make themselves either matter or not. Most people matter. But some make themselves a negative to their society, thus making their lives not matter and their death a positive.
Be sure to work hard and get lots of overtime. People on welfare want more steaks and free upgrades to smart phones with unlimited data packages.
I believe human lives matter. But that's probably just "specie-ist" of me.
Are people really so confused by the "Black Lives Matter" slogan that they have to insist on this pedantic "Hurr durr I care about all lives!" distinction? Obviously the people who sport the slogan aren't saying that other peoples lives are less important. They are using the slogan because they believe there is an identifiable group of people who have been singled out for discrimination and terrible practices when it comes to their interactions with the police and that therefore their deaths should receive special attention to rectify this alleged injustice. "Black Lives Matter" is a response to a perceived injustice not some brainless belief that only 'black lives' matter.
