Thomas Aquinas was a Christian philosopher, theologian, and scientist in the 13th century A.D.
His best-known works are the Disputed Questions on Truth (1256-59), the Summa contra Gentiles (1259-1265), and the Summa Theologiae (1265-1274). His commentaries on Scripture and on Aristotle also form an important part of his body of work.
In his quote, Aquinas states that within every human-being derives a longing for fulfillment.
