It will be seen, also, that *with the growth of knowledge, conscience has a constantly wider scope of action*. The number of indifferent acts is thus diminished; the number of positively right or wrong acts, increased. An _indifferent_ act is one for the performance of which, rather than its opposite, no reason, involving a question of right or wrong, can be given. Thus, if the performance or the omission of a specific act be equally fitted to the time, place, circumstances, and persons concerned, the act is an indifferent one; or, if two or more ways of accomplishing a desired end be equally fitted to time, place, circumstances, and persons, the choice between these ways is, morally speaking, a matter of indifference. But with a knowledge both more extensive and more minute of the nature, relations, and fitnesses of beings and objects, we find an increasing number of instances in which acts that seemed indifferent have a clearly perceptible fitness or unfitness, and thus acquire a distinct moral character as right or wrong. Section III. Sources Of Knowledge. 2. Law. *Law is the result of the collective experience*, in part, of particular communities, in part, of the human race as a whole. It encourages, protects, or at least permits whatever acts or modes of conduct have been found or believed to be fitting, in accordance with the nature of things and the well-being of men, and therefore right; it forbids and punishes such acts or modes of conduct as have been found or believed to be unfitting, opposed to nature and to human well-being, and therefore wrong. It is far from perfect; it is below the standard of the most advanced minds; but it represents the average knowledge or belief of the community to which it belongs. *The laws* of any particular state cannot rise far above this average; for laws unsustained by general opinion could not be executed, and if existing in the statute-book, they would not have the nature and force of law, and would remain on record simply because they had lapsed out of notice. Nor can they fall far below this average; for no government can sustain itself while its legislation fails to meet the demands of the people.
