Tropes, figures and symbols

Why do we fall in love with certain tropes, figures and symbols from literature, movies, e.g. and carry them with us, so that they are passed on to the next generation? Why do we pass symbolic meaning, figures and tropes from  generation to generation?

Can we sense that they are important in regards to our working life and aspirations with regards to writing, thinking, reading and engaging in conversation and thereby hold on to them?

Is it because we always strive to make sense of things in our vicinity, unify things in seamless patterns that please our need for coherence and symmetry?

Is our affinity for certain tropes e.g. connected with our immediate lifeworld and knowledge horizon, for instance pop culture?

Does the figures, symbols and tropes on a deeper level carry meaning that reflect our inner desires or immediate needs?

What is left behind? The tropes, symbols and figures that aren’t malleable enough to adjust to the requirements of new generations?
