Progressive

In the view of George Lakoff, "the progressive worldview is modeled on a nurturant parent family. Briefly, it assumes that the world is basically good and can be made better and that one must work toward that. Children are born good; parents can make them better. Nurturing involves empathy, and the responsibility to take care of oneself and others for whom we are responsible. On a larger scale, specific policies follow, such as governmental protection in form of a social safety net and government regulation, universal education (to ensure competence, fairness), civil liberties and equal treatment (fairness and freedom), accountability (derived from trust), public service (from responsibility), open government (from open communication), and the promotion of an economy that benefits all and functions to promote these values, which are traditional progressive values in American politics." 

Contrasting the progressive with the conservative worldview
Contrast with his description of a conservative worldview, from the same source. "the strict father model, assumes that the world is dangerous and difficult and that children are born bad and must be made good. The strict father is the moral authority who supports and defends the family, tells his wife what to do, and teaches his kids right from wrong. The only way to do that is through painful discipline -- physical punishment that by adulthood will become internal discipline. The good people are the disciplined people. Once grown, the self-reliant, disciplined children are on their own. Those children who remain dependent (who were spoiled, overly willful, or recalcitrant) should be forced to undergo further discipline or be cut free with no support to face the discipline of the outside world."

Origins of the term "progressive
Later,  "The term "progressive" originated from people who were Democratic Socialists, but the socialism aspect has dropped away, and it's come to mean what I call "nurturant morality." It includes choosing peace whenever possible, environmentalism, civil liberties, minority rights, notions like social justice through living wages, et cetera."
