Quote by Thomas Aquinas
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.
Summary
This quote suggests that while it may not be possible to prove God's existence through reason alone (a priori), one can still provide evidence and demonstrate it through observation and experience (a posteriori). It implies that by examining the tangible aspects of God's creation or the effects of His actions that are known to us, we can come to a more certain understanding of His existence. Through this approach, it suggests that faith can be supported and strengthened by exploring the concrete manifestations of the divine.
