Yours for the unshackled exercise of every faculty by every human being.

The line reads like a valediction or sign-off in a letter, framing the speaker’s allegiance as a commitment to universal human development. “Unshackled exercise” suggests both political emancipation (freedom from slavery, legal constraint, or coercion) and intellectual/spiritual liberty (freedom of thought, conscience, and self-cultivation). By insisting on “every faculty” and “every human being,” the sentiment is radically egalitarian: the full range of human capacities—moral, mental, creative, and practical—should be available to all, not reserved for a privileged class, race, or sex. In Child’s reformist idiom, the phrase functions as a compact credo for human rights and anti-oppression activism.
