Jane Addams was also a philosopher of peace. Peace theorists often distinguish between negative and positive peace. Negative peace deals with the absence of violence or war. Positive peace is more complicated. It deals with the kind of society we aspire to, and can take into account concepts like justice, cooperation, the quality of relationships, freedom, order and harmony. Jane Addams's philosophy of peace is a type of positive peace. Patricia Shields and Joseph Soeters (2017) have summarized her ideas of peace using the term "Peaceweaving". They use weaving as a metaphor because it denotes connection. Fibers come together to form a cloth, which is both flexible and strong. Further, weaving is an activity in which men and women have historically engaged. Addams "peaceweaving" is a process which builds "the fabric of peace by emphasizing relationships. Peaceweaving builds these relationships by working on practical problems, engaging people widely with sympathetic understanding while recognizing that progress is measured by the welfare of the vulnerable"
