“Happiness and Misery must inevitably increase with increasing Power and Knowledge”
Letter to Lewis Campbell (9 November 1851) in Ch. 6 : Undergraduate Life At Cambridge October 1850 to January 1854 — ÆT. 19-22, p. 158
The Life of James Clerk Maxwell (1882)
Context: I believe, with the Westminster Divines and their predecessors ad Infinitum that "Man's chief end is to glorify God and to enjoy him for ever."
That for this end to every man has been given a progressively increasing power of communication with other creatures.
That with his powers his susceptibilities increase. That happiness is indissolubly connected with the full exercise of these powers in their intended direction. That Happiness and Misery must inevitably increase with increasing Power and Knowledge. That the translation from the one course to the other is essentially miraculous, while the progress is natural. But the subject is too high. I will not, however, stop short, but proceed to Intellectual Pursuits.
