Fountain from Third Dialogue

 

This illustration of Hylas and Philonous conversing by a fountain is taken from an early edition of the Three Dialogues and represents the concluding scene of the Third Dialogue. (From Images of Berkeley.)

You see, Hylas, the water of yonder fountain, how it is forced upwards, in a round column, to a certain height; at which it breaks and falls back into the basin from whence it rose: its ascent as well as descent, proceeding from the same uniform law or principle of gravitation. Just so, the same principles which at first view lead to scepticism, pursued to a certain point, bring men back to common sense. (Luce and Jessop, Vol. II, pp. 262-263)
