By Camille Flammarion
N’est-il pas agréable d’exercer notre esprit dans los angeles contemplation des grands spectacles de l. a. nature ? N’est-il pas utile de savoir au moins sur quoi nous marchons, quelle position nous occupons dans l’infini, quel est ce soleil dont les rayons bienfaisants entretiennent l. a. vie terrestre, quel est ce ciel qui nous environne, quelles sont ces nombreuses étoiles qui pendant l. a. nuit vague répandent dans l’espace leur silencieuse lumière ?
