Quote by Jean le Rond d'Alembert
If one looks at all closely at the middle of our own century, the events that occupy us, our customs, our achievements and even our topics of conversation, it is difficult not to see that a very remarkable change in several respects has come into our ideas; a change which, by its rapidity, seems to us to foreshadow another still greater. Time alone will tell the aim, the nature and limits of this revolution, whose inconveniences and advantages our posterity will recognize better than we can.
Summary
This quote suggests that in the middle of the 20th century, there was a noticeable shift in our ideas, customs, achievements, and discourse. It implies that this change is significant and rapid, and even indicates that it may be the precursor to an even bigger revolution. The true implications, goals, nature, and boundaries of this revolution will only become clear with time, and it is likely that future generations will have a better understanding of its merits and drawbacks than we do.
