"It is possible to demonstrate God's existence, although not a priori, yet a posteriori from some work of His more surely known to us"

This quote by Thomas Aquinas suggests that it is possible to show the existence of God, but not through a priori thinking, which is based on abstract thinking and sensible deduction. Rather, Aquinas suggests that it is possible to prove the existence of God a posteriori, which is based on empirical evidence and experience. To put it simply, Aquinas suggests that we can show the existence of God through the works of God that are more quickly understood to us. This could consist of the charm of nature, the intricacy of deep space, or the ethical laws that govern our lives. Aquinas recommends that these works of God can be utilized to show the existence of a greater power, and that this is a more trustworthy way of showing the existence of God than a priori thinking.
