The general question to which this paper is addressed is whether knowledge and rationality carry within themselves the seeds of their own destruction. Some of those who set out in search of knowledge come to believe as a result of their inquiries that the object of their quest is not what they had taken it to be; seeking to discover the way the world actually is, they are led to conclude that all they can hope to find is a reflection of their own needs and interests; the grail is but a beaker. Similarly, some of those whose aim is to formulate the principles of rational thought are led by reason to deny that any beliefs can be rationally justified; reasons are never reasons for believing but mere epiphenomena, produced by but not producing events whose only begetter is the passions; the quest is just another power struggle. The particular question I wish to ask is whether this picture is an accurate representation of social inquiry.
