Throughout his years, Edmund Burke generated a prolific library of writings that are foundational to Conservative thinking and kept England on course away from Revolution.
Conservatives seek to conserve the traditions and ideas man has learned to be good through the centuries. Radicals seek change for change's sake.
George Santayana had a rich depth of conservative ideas that identified and fought against the materialism of the modern world.
The conservative is ultimately concerned with just what effect a new idea or policy will have on the societal order. Radicals are so insistent on change for the sake of change that they cannot comprehend what their ideas will ultimately do to the bonds that connect generation to generation.
In the late 20th century, conservatives in both America and England faced a crisis of leadership and ideas. It seems the radicals are destined to win, but they are always met with challengers that break the very foundations of the radical's ideas.
