The Pure Intellect
87. When in a pure state, the intellect, on receiving the conceptual images of things, is moved to contemplate these things spiritually. But when it is sullied through indolence, while its conceptual images may in general be free from passion, those concerned with people produce in it thoughts that are shameful or wicked.
St. Maximus the Confessor Four Hundred Centuries on Love: #87
Maximus the Confessor explains that a pure intellect, when receiving conceptual images of things, is moved to contemplate them spiritually. However, if sullied through indolence, even generally passion-free images concerning people can produce shameful or wicked thoughts.
Imagine a pristine mirror, reflecting the world with perfect clarity. When the mirror is clean, it accurately represents reality. However, if it becomes dirty, the reflections are distorted and unclear. The intellect, when pure, can contemplate spiritual truths with clarity. But if it becomes sullied by laziness or neglect, even benign images can be tainted, leading to impure thoughts.
Maintaining a pure intellect requires vigilance and discipline. By keeping our minds focused on God and nurturing our spiritual practices, we can ensure that our intellect remains clear and capable of deep, spiritual contemplation.
