There is no general agreement among scholars on how to periodize the various quests for the historical Jesus. Most scholars agree the first quest began with Reimarus and ended with Schweitzer, that there was a "no-quest" period in the first half of the twentieth century, and that there was a second quest, known as the "New" quest that began in 1953 and lasted until 1988 when a third began. However, Stanley E. Porter (b. 1956) calls this periodization "untenable and belied by all of the pertinent facts", arguing that people were searching for the historical Jesus before Reimarus, and that there never has been a period when scholars weren't doing so.
