Explanation:

In 1908 Woodrow Wilson wrote Constitutional Government in the United States. In it, he argued that we should see the Constitution as something that changes with the needs of the people, something that allows reforms. He believed the government should be looked at "under the theory of organic life.""Accountable to Darwin, not to Newton." In other words, something that should evolve, not be looked at as a non-bending,non-changing set of rules. Eternal vigilance is needed to watch for changes that may not serve the good of the people. Things can slip over time in tiny increments that may not be noticed until things are far off the path. This passage seems to infer that we should watch for those "Darwinian" changes to assure that they do not take us off the path to liberty.
