Who are those others, ever learning, and never able to come to the knowledge of the truth? (II Tim. 3:7). … those who, having entered the realm of faith, do nothing but invent questions—“What is this? What is that? Why this way? Why that way?” They are people suffering from empty inquisitiveness. They do not chase after the truth, only ask and ask. And having found the answer to their questions, they do not dwell on them for long, but soon feel the necessity to look for another answer. And so they whirl about day and night, questioning and questioning, and never fully satisfied with what they learn. Some people chase after pleasures, but these chase after the satisfaction of their inquisitiveness.
St. Theophan the Recluse
