As one works through the degrees, one studies the lessons and interprets them for oneself. There are as many ways to interpret the rituals as there are Masons, and no Mason may dictate to any other Mason how he is to interpret them. No particular truths are espoused, but a common structure—speaking symbolically to universal human archetypes—provides for each Mason a means to come to his own answers to life's important questions. Especially in Europe, Freemasons working through the degrees are asked to prepare papers on related philosophical topics, and present these papers in an open Lodge, where others may judge the suitability of the candidates' ascension through the higher degrees.
