We need to let our children grow up to face the world armed with knowledge, with much more knowledge than we ourselves had at their age. It is scary, but the alternative is worse.
Wherever there is a design that is highly successful in a broad range of similar environments, it is apt to emerge again and again, independently - the phenomenon known in biology as convergent evolution. I call these designs 'good tricks.'
Interpretation
What this quote means
Great designs in nature often reappear independently in similar contexts, a principle known as convergent evolution.
The quote by Daniel Dennett suggests that certain successful designs arise repeatedly across different contexts due to their inherent effectiveness, much like the biological principle of convergent evolution where different species develop similar traits in response to similar challenges. He refers to these effective designs as 'good tricks,' highlighting the idea that useful solutions tend to recur in various forms across nature and invention.
Themes
In practice
Example use cases
During a talk on innovation, one could use this quote to illustrate how effective solutions surface across various fields.

Words have a genealogy and it's easier to trace the evolution of a single word than the evolution of a language.
The secret of happiness is: Find something more important than you are and dedicate your life to it.
Some philosophers can't bear to say simple things, like "Suppose a dog bites a man." They feel obliged instead to say, "Suppose a dog d bites a man m at time t," thereby demonstrating their unshakable commitment to logical rigor, even though they don't go on to manipulate any formulae involving d, m, and t.
As every scuba diver knows, panic is your worst enemy: when it hits, your mind starts to thrash and you are likely to do something really stupid and self-destructive.

Physics is an otherworld thing, it requires a taste for things unseen, even unheard of- a high degree of abstraction... These faculties die off somehow when you grow up... profound curiosity happens when children are young. I think physicists are the Peter Pans of the human race... Once you are sophisticated, you know too much- far too much. Pauli once said to me, "I know a great deal. I know too much. I am a quantum ancient.".
I cannot but be astonished that Sarsi should persist in trying to prove by means of witnesses something that I may see for myself at any time by means of experiment. Witnesses are examined in doutbful matters which are past and transient, not in those which are actual and present. A judge must seek by means of witnesses to determine whether Peter injured John last night, but not whether John was injured, since the judge can see that for himself.
To set foot on the soil of the asteroids, to lift by hand a rock from the Moon, to observe Mars from a distance of several tens of kilometers, to land on its satellite or even on its surface, what can be more fantastic? From the moment of using rocket devices a new great era will begin in astronomy: the epoch of the more intensive study of the firmament.
In space there are countless constellations, suns and planets; we see only the suns because they give light; the planets remain invisible, for they are small and dark. There are also numberless earths circling around their suns.
