This quote envisions a future society where the regulation of sexual relations rests entirely on the private will of the individuals involved, rather than on public sentiment or legal restrictions. The idea that love and physical relationships should transcend societal or legal constraints challenges traditional moral norms and underscores the primacy of personal freedom and autonomy.

Reflecting on this, it becomes clear that such a perspective anticipates many contemporary discussions around personal liberty and consensual relationships. By proposing that "every man or woman" should have "entire freedom" to follow their private affections, the quote elevates individual choice as a fundamental principle. It breaks away from collectivist ideas that often control or restrict personal relationships, highlighting a vision for a society founded on mutual respect and voluntary alliances.

This belief carries significant implications about the role of law and public opinion in personal spheres. Typically, laws governing sexual relations reflect prevailing moral attitudes and social structures—sometimes dictating marriage, sexuality, and other intimate behaviors. The idea that these laws could ultimately become obsolete or secondary to private consent speaks to a profound shift towards recognizing personal autonomy as sacrosanct.

Moreover, the quote subtly touches upon the evolving nature of public sentiment. Instead of repressing individual desires, societal attitudes might come to support and justify various forms of alliances so long as they are genuinely consensual. This progression could lead to greater inclusivity and acceptance, breaking down prejudices that historically marginalized certain relationships or identities.

However, this vision also demands a nuanced appreciation of freedom. True liberty in sexual relations requires individuals to have the capacity and safety to express their wills without coercion, manipulation, or inequity. It suggests a hopeful endpoint where society protects these freedoms and trusts individuals' capacity to responsibly govern their intimate partnerships.

Overall, this quote challenges us to rethink the balance between individual freedom and social regulation, showing a forward-thinking embrace of personal agency and authenticity in human relationships.
