There is a recent article in which Rabbi Moishe Bane writes the following :

The legendary Chief Rabbi Avraham Yitzchok KaCohen Kook z”l, observed that in every society, in every religion, in every country, in every era throughout history, there is a remarkable inverse correlation between a community’s level of education and sophistication and the degree of its religious intensity. The more educated a community, the less vigorous its religious commitment. Is this observation not evidence, asked Rav Kook, that religion generally appeals only to the most primitive minds? Doesn’t this inverse correlation prove that we, as sophisticated individuals, should recognize the folly of a commitment to, and passion for, Torah Judaism?  Rav Kook explained that every society, in every religion, in every country, in every era throughout history, provides their youth with roughly the equivalent of a third grade religious education. Consequently, in those societies in which that third grade religious education is accompanied by a third grade secular education, the youth mature into adulthood satisfied with their understanding of religion. By contrast, when a community receives a third grade religious education, but then goes on to receive a high school, university and an even more advanced secular education, they consider the simplistic nature of religion, as they had been taught, and dismiss religion as being primitive.

Where can I find Rav Kook writing such a thing?
