How does John Cage’s notion of chance in Silence (1961) compare to Bergson’s in Two Sources of Morality and Religion (1932)?

Chance has been defined as luck, superstition, risk, probability and accidental. The historical narrative of chance is of intelligent minds trying to grasp the uncertain and use it to their advantage (Everett, 2008, p. 6). Chance is a force that humans seek to control, in the forms of risk and gambling (p. 4). While these tactics were medieval and unknown, they had a great relation to sacred texts and literature where chance was used as a communication with a greater power (p. 5). It was used to determine justice in the judicial system, for entertainment, and other means to demonstrate favour with the gods (p. 5). These days, chance has evolved systems to combat the uncertain, for example using risk assessment to preserve human life and probability in mathematics (p. 6).
