The reduct A' of an experience A might be regarded as the outcome of a phenomenological reduction, the identical experience as retained after the suspension of the natural attitude, or it might be seen more simply as the experience undergone from a detached position with all judgment suspended, as the same experience disidentified, viewed or reflected with the understanding that it is wholly within consciousness, that every transcendental element in it is so because of a prior immanence. In all these broader senses, or their overlapping, the reduction is not only a technicality of phenomenology but an intrinsic aspect of experience in general, corresponding to its reflectibility, or its significance. The question then arises as to what it is that is changed, what is A - A'? This is undoubtedly a possible object of reflection, and itself an intimate component of experience.
