Ishida Baigan (October 12, 1685 - October 29, 1744) was a Japanese lecturer and philosopher who founded the Shingaku movement (heart learning) which advocated all education include teachings in ethics and morality.
His life work in today's perspective has been summarized with the Confucian idea that a man that cannot control his home cannot control his nation. This idea helped motivate many Japanese reformists fighting for Japanese feminists, human, and people's rights.
