So multifarious are the different classes of truths, and so multitudinous the truths in each class, that it may be undoubtingly affirmed that no man has yet lived who could so much as name all the different classes and subdivisions of truths, and far less anyone who was acquainted with all the truths belonging to any one class. What wonderful extent, what amazing variety, what collective magnificence! And if such be the number of truths pertaining to this tiny ball of earth, how must it be in the incomprehensible immensity!
Horace Mann (1867). “Thoughts”, p.61
