And this is why the laws of a science are also called conditions, because without complying with them we cannot produce a correct instance of a particular: e.g., from observation we enunciate the law, all water has, drowning properties. Now this is a condition upon which water's being water depends, for if a man pointed to some water and said, This water has no drowning properties, we should say, My good sir, this cannot be water, then, for it does not comply with the conditions required to constitute water.

Dyver, looking very subtle, here enquired whether science was the process of attaining to universal knowledge, or the knowledge so attained, for art seemed to be the process only, and Mr. Practical replied that it was difficult to say; he believed science was used for both, perhaps on the whole it was moreoften used for the knowledge attained, but it made very little difference to the broad distinction between science and art, and that was all he wanted to show. ' To give you an illustration of what I mean by science and art, I shall make a rough sketch with my pencil, ' he continued, scarcely a bit discomposed by the penetrating subtlety of his senior pupil. ...
