Purvis supported many progressive causes in addition to abolition. With Lucretia Mott, he supported women's rights and suffrage. When Mott was president, he was a member of the American Equal Rights Association. Purvis also attended the founding meeting of the Pennsylvania Woman Suffrage Association. He supported temperance and similar social issues. He believed in integrated groups working for greater progress for all. By the end of the Civil War, which gained the emancipation of slaves and suffrage for black men, Purvis had reached his late 50s and became less active in political affairs.
