Chapter XVIII's most controversial paragraph. Faith is binding only when the original reasons still hold. Where humans are bad actors, no obligation is unconditional; "legitimate reasons to excuse this non-observance" are always findable.
The argument structure: 1. Humans are mixed. (Working assumption; ch. XV specifies which mixes.) 2. The expectation that obligations are unconditional requires the counterpart to be principled regardless of consequences. 3. Therefore conditional obligation is the operative rule.
Not "anyone who wants to break faith, can." It's "anyone whose counterparties have already shown willingness to break faith, has no fixed obligation."
