Taken from The Guide for the Perplexed By Moses Maimonides

Another interesting quote

"This law can only be kept and perpetuated in its perfection, if circumcision is performed when the child is very young, and this for three good reasons. First, if the operation were postponed till the boy had grown up, he would perhaps not submit to it. Secondly, the young child has not much pain, because the skin is tender, and the imagination weak; for grown-up persons are in dread and fear of things which they imagine as coming, some time before these actually occur. Thirdly, when a child is very young, the parents do not think much of him; because the image of the child, that leads the parents to love him, has not yet taken a firm root in their minds. That, image becomes stronger by the continual sight; it grows with the development of the child, and later on the image begins again to decrease and to vanish. The parents' love for a new-born child is not so great as it is when the child is one year old; and when one year old, it is less loved by them than when six years old. The feeling and love of the father for the child would have led him to neglect the law if he were allowed to wait two or three years, whilst shortly after birth the image is very weak in the mind of the parent, especially of the father who is responsible for the execution of this commandment. "

Also how Jewish circumcision went from removing the very tip of the foreskin (Milah) to the full circumcision we see today (Periah).

I just thought I would submit this because I always hear how male circumcision is not used to control male sexuality when it's history shows us that is exactly what male circumcision is used for. I also thought it would be interesting to have a discussion revolving around religious circumcision since religion is often times accepted as reason enough to circumcise a child even when medical benefits are not.
