I would define it as the freedom to do what you ought

As this is literally an Orwellian definition (the totalitarian state of Nineteen Eighty-Four defined "freedom" as obedience to Big Brother), I cannot possibly take it seriously.

[The Ghost of FReepers Past]

So what keeps parents nurturing the child the choose to have? What obligates the individual who makes any choice to follow through with the responsibility of manging the results of that choice? The "ought" principle is just the responsibility principle. In many cases freedom applies to one choice -- the first choice -- which then leads to a long line of responsiiblities. Again libertarians try to separate truths as though they are not interrelated. ...and even as though there is no absolute truth. Without absolute truth, there is no real natural reason to think that freedom itself is the ultimate good. Survival of the fittest would be the natural thing.
