Prophecy
We will show that prophecy is not a vision of the future, for it is made up.
Shemita
We will show that determining the sabbatical year (the seventh year) was done based on Chazal's erroneous view of historical reality.
Mezuzah
We will show that synagogues, schools, universities…are exempt from having mezuzot.
Circumcision
We will clarify that the religious ceremony, between man and G-d, poses a danger to the infant's life and keeps him from sexual pleasure.
