The insightful declaration that nothing on this earth is more to be prized than true friendship comes from the brilliant mind of Thomas Aquinas. A Dominican friar and preeminent 13th-century philosopher and theologian (1225-1274), Aquinas, despite his imposing physical presence earning him the nickname "The Dumb Ox," possessed an intellect that shaped Western thought. This particular sentiment on friendship can be found in a shorter work he penned around 1267, titled *De regno ad regem Cypri*, or *On Kingship To The King of Cyprus*, where he explored the foundations of good governance and human flourishing.

For Aquinas, true friendship was far more than a casual acquaintance; it represented the ideal relationship rational beings should cultivate. He believed it to be the wellspring of the greatest pleasures, asserting that even the most agreeable pursuits become tedious without the companionship of friends (Review). At its core, this prized bond is rooted in an unselfish love, characterized by a constant and effective desire to do good for another, fostering a union of wills and a mutual goodwill that promotes virtue. This profound understanding meant friendship was not merely about shared opinions, but a deeper alignment of intentions and actions.

The enduring relevance of Aquinas's words echoes through history and modern life. His philosophy on friendship extends beyond human relationships to encompass a profound connection with the divine, seeing charity as a form of friendship with God. In the secular realm, the power of true friendship is evident in the lives of figures like C.S. Lewis and the Oxford Inklings, whose intellectual and spiritual growth was deeply nurtured by their close-knit fellowship, even influencing Lewis's return to faith. Aquinas reminds us that these invaluable connections are a universal human need, providing support in adversity and enriching every aspect of our lives, making them truly among the most cherished treasures on earth.
