Quote by Douglas Adams, Last Chance to Se
Human beings, who are almost unique in having the ability to learn from the experience of others, are also remarkable for their apparent disinclination to do so.
Summary
This quote suggests that humans possess the remarkable quality of being able to learn from the experiences of others, which sets them apart from other beings. However, it also highlights the paradoxical aspect of humanity's behavior in that they seem reluctant or indifferent to actually utilizing this ability. In other words, despite having the opportunity to gain wisdom from the mistakes or successes of others, humans often fail to take advantage of this potential for growth and improvement.
