Intellectual pleasures are, perhaps, the hast generally known of all those which our nature can enjoy. For the great majority of the human race is made up of the poor, who are compelled to spend their lives in toiling for food and raiment. They are, in consequence, unable to develop their mental faculties and to enjoy high intellectual pleasures. And yet these pleasures are the highest, the most rational and satisfying which man can enjoy; because they are produced by the exercise of the intellect, which is the noblest faculty of the soul. Men of highly cultivated minds, such as theologians, philosophers, astronomers, mathematicians, and literary men, separate themselves from the world and its pleasures; they spend the day, and a great part of the night, in study, in the contemplation of the truth; they even forget to eat and drink, and must be compelled by their friends to attend to the necessities of nature. Many of them have completely ruined their health by study; and some of them, as Democritus the philosopher, are reported to have even plucked out their eyes, that they might have less distraction, and thereby be enabled to meditate more profoundly upon the truths of their respective sciences. Now, I ask, is it in our nature to go through such terrible self-denials without compensation? Surely it is not. Therefore, the natural inference is that knowledge is a source of the most exquisite pleasures. If it is so, in this world, where the curse of sin has darkened the mind, and where knowledge is so limited, and so mingled with error and doubt, what shall we say of those pleasures in heaven? There the intellect of man receives a supernatural light; it is elevated far above itself by the light of glory; it is purified, strengthened, enlarged, and enabled to see God as He is in His very essence. It is enabled to contemplate, face to face, Him who is the first essential Truth. It gazes undazzled upon the first infinite beauty, wisdom, and goodness, from whom flow all limited wisdom, beauty, and goodness found in creatures. Who can fathom the exquisite pleasures of the human intellect when it thus sees all truth as it is in itself? This is one of heaven's secrets which we shall never fully understand, except when united to God in the Beatific Vision. Nevertheless, if ever we have enjoyed the pleasures produced by the perusal of a highly intellectual work, or felt the irresistible fascinations of some favorite science, we can, it seems, form some distant conception of intellectual pleasures in heaven.
