“We are not gods, and we are not omniscient. We cannot foretell the future with certainty. Most often, cultural and political changes are terribly complex. It can be notoriously difficult to predict exactly where a trend will take us, and we can be mistaken. We do the best we can: if we wish to address certain issues seriously, we study history, and we read everything that might shed light on our concerns. We consult what the best thinkers of our time and of earlier times have said and written. We challenge everyone’s assumptions, including most especially our own. That last is often very difficult. If we care enough, we do our best to disprove our own case. In that way, we find out how strong our case is, and where its weaknesses may lie.
Barring extraordinary circumstances, we cannot be certain that a particular development represents a critical turning point at the time it occurs. If we dare to say, “This is the moment the battle was lost,” only future events will prove whether we were correct. We do the best we can, based on our understanding of how similar events have unfolded in the past, and in light of our understanding of the underlying principles in play. We can be wrong.”
