Every right implies the opposite. There is no freedom without limitation. The freedom of speech implies that others haven’t the right to censor.
Libertarianism tends to be too corpuscular, too egocentric, to not recognize that every individual is inextricably bound to others.
There is no ‘I’ except there be a “you,” a “she,” a “he,” or a “they.” This recognition leads to a philosophy which looks carefully at the “we,” and thinks carefully of how we might maximize freedom for all.
