List of Talmudic principles
（重定向自Migo）
The Talmud uses many types of logical arguments.
A Chazakah (Hebrew:חזקה) usually refers to the default assumption; i.e. what is assumed until there is evidence to the contrary. For example, if one is known to have owned property, it is assumed that he still owns it until proven otherwise. However, with movable items, the Chazakah lies with whoever currently has the item in his possession, not with the one who had previously owned it.
