Since we're determined—caused —to make causal inferences, then if they aren't “determin'd by reason”, there must be “some principle of equal weight and authority” that leads us to make them. Hume maintains that this principle is custom or habit:
whenever the repetition of any particular act or operation produces a propensity to renew the same act or operation … we always say, that this propensity is the effect of Custom. (EHU 5.1.5/43)

It is therefore custom, not reason, which “determines the mind … to suppose the future conformable to the past”... SEP
