Hume
Strange Encounters
One of my favorite passages from Hume actually occurs twice – in the Treatise and the Enquiry. This is the passage where Hume offers up the example of the man with normally functioning faculties who is suddenly placed into a strange, unfamiliar environment. This is the lesson Hume draws from this thought experiment:
For ‘tis evident, that if a person full-grown, and of the same nature with ourselves, were on a sudden transported into our world, he wou’d be very much embarrass’d with every object, and would not readily find what degree of love or hatred, pride or humility, or any other passion he ought to attribute to it. The passions are often vary’d by very inconsiderable principles; and these do not always play with a perfect regularity, especially on the first trial. But as custom and practice have brought to light all these principles, and have settled the just value of every thing; this must certainly contribute to the easy production of the passions, and guide us, by means of general establish’d maxims, in the proportions we ought to observe in preferring one object to another. (T 2.1.6, 293-4)
In the Enquiry Hume slightly modifies the example:
Suppose a person, though endowed with the strongest faculties of reason and reflection, to be brought on a sudden into this world; he would, indeed, immediately observe a continual succession of objects, and one event following another, but he would not be able to discover any thing farther. He would not, at first, by any reasoning, be able to reach the idea of cause and effect; since the particular powers, by which all natural operations are performed, never appear to the senses; nor is it reasonable to conclude, merely because one event, in one instance, precedes another, that therefore the one is the cause, the other the effect. Their conjunction may be arbitrary and casual. There may be no reason to infer the existence of one from the appearance of the other. And in a word, such a person, without more experience, could never employ his conjecture or reasoning concerning any matter of fact, or be assured of any thing beyond what was immediately present to his memory and senses. (EHU 36).
