Butler begins Precarious Life in recognition that vulnerability, both physical and social, is a reality of life and thus cannot be argued against, though there are many ways of thinking about this vulnerability, which can be argued.

Humans are physically vulnerable beings by virtue of being mortal and are born into a state of “primary vulnerability,” beginning life as entirely physically and socially reliant on others. While individuals can “achieve” a level of autonomy, they never become fully autonomous, nor does Butler think that unequivocal autonomy is something to be desired.
