The world-outlook that grants reality to nothing except bare sense-impressions, keeping the senses' report and discarding whatever mind adds to it.
Sensationalism is the standpoint Rudolf Steiner names for the soul that trusts the senses alone. Such a thinker grants that phenomena surround us, yet treats every order the mind seems to find in them as a private addition. What remains, once thought is peeled away, is the raw sense-impression, taken as the one honest signal that reality sends us.
In Steiner's Own Words
Note well that a person who says this is not a follower of phenomenalism, but rather strips away from the phenomenon what he believes comes only from the mind and reason, and accepts as somehow announced by reality what the senses give as impressions. This worldview can be called sensualism.
What it Means Today
Steiner did not coin Sensationalism in a vacuum. He was naming, in spiritual-scientific terms, the sensory pole of British empiricism. John Locke set the keynote in his 1690 Essay Concerning Human Understanding: nothing reaches the understanding that did not first pass through sense, and the mind begins as blank paper written on by experience. David Hume pressed the line to its edge, tracing every idea back to an antecedent impression and dissolving causation, substance, even the self into habits of sensory association. John Stuart Mill, two centuries on, defined matter itself as "the permanent possibility of sensation," which is Steiner's standpoint stated almost word for word. Reading this lineage through GA 151 shows why Steiner placed Sensationalism beside its neighbours rather than against them. It is sharper than Phenomenalism, which still lets the appearance stand as appearance; the sensationalist goes further and keeps only the impression, distrusting whatever the understanding seems to supply. Yet it stops just short of Materialism: the instant a thinker declares those impressions to be matter, as Steiner shows, the standpoint topples into the materialist camp by a second road. The Thalira reading is that Sensationalism is true within its own narrow field and false only when made total. The senses do deliver a genuine message; the error is amputating thinking from that message, mistaking one of the twelve gateways for the whole horizon. Held among its eleven companions, rather than absolutised, it keeps its proper Leo place in the circle.
