描述Modus Fresison.svg	One of the 24 syllogisms listed below. The deduction is represented by a 3 circle Venn diagram. Premises and the logical consequence are represented by 2 circle Venn diagrams. The left circle stands for S, the top circle for M, and the right circle for P. Areas marked in black are empty - there are no elements in these areas. In red areas there is at least one element, represented by an x. White areas are not important for the deduction, and nothing is told about them. There may be elements or not.
