A.E. Housman, inaugural lecture
, University College, London, 1892:
The faculty of learning is ours that we may find in its exercise that delight which arises from the unimpeded activity of any energy in the groove nature meant it to run in. Let a man acquire knowledge not for this or that external and incidental good which may chance to result from it, but for itself; not because it is useful or ornamental, but because it is knowledge, and therefore good for man to acquire. 'Brothers,' says Ulysses in Dante, when with his old and tardy companions he had left Seville on the right hand and Ceuta on the other, and was come to that narrow pass where Hercules assigned his landmarks to hinder man from venturing farther: 'Brothers, who through a hundred thousand dangers have reached the West, deny not, to this brief vigil of your senses that remains, experience of the unpeopled world behind the sunset. Consider of what seed ye are sprung: ye were not formed to live like brutes, but to follow virtue and knowledge.' For knowledge resembles virtue in this, and differs in this from other possessions, that it is not merely a means of procuring good, but is good in itself simple: it is not a coin which we pay down to purchase happiness, but it has happiness indissolubly bound up with it.
It is the glory of God, says Solomon, to conceal a thing: but the honour of kings is to search out a matter. Kings have long since abdicated that province; and we students are come into their inheritance: it is our honour to search out the things which God has concealed. In Germany at Easter time they hide coloured eggs about the house and the garden that the children may amuse themselves in hunting after them and finding them. It is to some such game of hide-and-seek that we are invited by that power which planted in us the desire to find out what is concealed, and stored the universe with hidden things that we might delight ourselves in discovering them. And the pleasure of discovery differs from other pleasures in this, that is shadowed by no fear of satiety on the one hand or of frustration on the other. Other desires perish in their gratification, but the desire of knowledge never: the eye is not satisfied with seeing nor the ear filled with hearing. Other desires become the occasion of pain through dearth of the material to gratify them, but not the desire of knowledge: the sum of things to be known is inexhaustible, and however long we read we shall never come to the end of our story-book. So long as the mind of man is what it is, it will continue to exult in advancing on the unknown throughout the infinite field of the universe; and the tree of knowledge will remain for ever, as it was in the beginning, a tree to be desired to make one wise.
The Dante quotation is from the Inferno
"O frati", dissi "che per cento milia
perigli siete giunti a l'occidente,
a questa tanto picciola vigilia
d'i nostri sensi ch'è del rimanente,
non vogliate negar l'esperienza,
di retro al sol, del mondo sanza gente.
Considerate la vostra semenza:
fatti non foste a viver come bruti,
ma per seguir virtute e canoscenza."
The Solomon quotation is from Proverbs
