His desire is only to bestow good. Even evil is a means through which He bestows good. In this way His oneness is clearly revealed.
His Will is only good — and evil is itself a means through which the good is bestowed.
Op. 1 declared the strong oneness of His Will and immediately raised an objection it could not answer alone: if His Will is only good, what about evil? If the world is full of evil, either His Will is not all-good, or it is not all-controlling. Op. 2 answers the objection in a way that becomes the doctrinal seed of everything else in the book. The answer, in compressed form: evil is real, but it is real as a means. He created it precisely so that it could be overcome, and through the overcoming His goodness is revealed in a way that an evil-free world could never have shown.
The natural assumption is that evil is a flaw — a problem in the system, something to be regretted. Ramchal's move is to refuse this. Evil, in his view, is built into the cosmic plan from the start, not as a competitor to the good but as the very stage on which the good will be displayed. Without darkness, the lighting of a lamp is not a revelation; it is just the way things have always been. With darkness, the lighting of a lamp is an act, and the act shows the lamp's nature in a way no static brightness ever could.
The same is true at the cosmic scale. A world made entirely of good would be a world in which His goodness is assumed. A world made of good and evil — where the evil is overcome by the good — is a world in which His goodness is demonstrated. The demonstration is the point. This is why the cosmic plan calls for a cycle: a beginning in which good and evil are both present, a middle in which the good wrestles with the evil and gradually overcomes it, and an end in which the overcoming is complete and the good is seen to be the only standing reality. Evil, in this picture, is a temporal phenomenon — real for the duration of the cycle, dissolved at its close.
This position has a stronger consequence than first appears. If evil is a means, then evil has no independent footing. It is not a rival sovereign; it is not a parallel power; it is not an additional fact about the cosmos that His goodness has to accommodate. It is part of the cosmos His goodness has set up, with a specific role and a specific terminus. The Other Side (sitra achra) — the realm of evil that the rest of the book will treat extensively — is therefore bounded, created, and destined to revert to good. None of those qualifications softens the strong oneness of Op. 1; together they explain why the strong oneness is consistent with the realm of evil.
One further note. Ramchal's argument here is not that evil is not really evil — it is. The cycle's middle phase is not painless or fictional. People suffer; injustice happens; the wrestling is not a metaphor. The argument is about the cosmic reading of the wrestling: that it has a structural place, a structural purpose, and a structural endpoint. The pastoral comfort comes not from minimising what evil is but from locating it properly within the cycle of bestowal.
Op. 30 will operationalise this claim cosmogonically: the very act by which the cosmos was made (the Tzimtzum) embedded both the rule of good-and-evil and the rule of unity from the outset. And Op. 49 will name the temporal arc explicitly — six millennia as one cycle, with evil's role real, bounded, and reverting to good at the close. Reading Op. 2 with those two landmarks in view shows that the doctrinal claim made here is the structural form of the whole book.
