The struggle for individual advancement and development can be brought to naught, or indefinitely retarded, by the absence of law or by bad law.

Context

“When I say, that, even after we have all the good laws necessary, the chief factor in any given man's success or failure must be that man's own character, it must not be inferred that I am in the least minimizing the importance of these laws, the real and vital need for them. The struggle for individual advancement and development can be brought to naught, or indefinitely retarded, by the absence of law or by bad law. It can be immeasurably aided by organized effort on the part of the State. Collective action and individual action, public law and private character, are both necessary. It is only by a slow and patient inward transformation such as these laws aid in bringing about that men are really helped upward in their struggle for a higher and a fuller life.” source
