Final answer:
The sentiment of E. M. Forster towards causes cannot be determined from the provided reference to William James's indeterminism. A direct source from Forster himself would be needed to accurately reflect his views on causes.
Step-by-step explanation:
The sentiment of E. M. Forster towards the concept of causes is not explicitly mentioned in the provided reference to William James's view on indeterminism. Forster's own viewpoints would need to be examined through his writings or commentary on indeterminism to determine his stance on the significance or support for the notion of causes. Without a clear reference to Forster's views, one could assume that making a statement on his sentiment would be speculative. Moreover, since the original question seems to be about E. M. Forster but gives information about William James, there is a mismatch in the information provided.
William James's concept of indeterminism suggests that not all events are predetermined and that there might be room for uncaused events, giving way to free will and individual responsibility. We cannot equate James's philosophy directly to Forster's views without additional context or evidence of Forster's opinions on the matter of causes.
