Hearing is direct, immediate; we feel it in our ears.Vision objectifies the world; hearing opens the door to language and feeling. To listen to someone and to look for them are very different things, for no one can be invisible, and yet everyone, to be heard, must first speak. To listen is to be passive, to look, active. In all these ways, SETI seems more auditory, less visual. It needs no numbers or catalogues; it needs no equations or calculations. In the end it is not a study of the universe, but a communication with something we cannot know until it speaks

Intr-adevar, astronomul are o perspectiva unica asupra lumii extraterestre, accentuata de "ochii" pamanteni, super-tehnologizati si superiori ochiului uman, aceste creatii minunate ce "vad" mai departe decat si-ar imagina omul de rand - telescoapele ultra-performante.
Omul de rand nu stie nimic de organizarea stelelor, de constelatii, de numele lor, de numarul lor, de orbitele lor... el vede doar niste puncte, niste forme, niste culori si le contempleaza...
Deci, una e sa le vezi ca astronom, alta e sa le vezi ca un copil.
