The Perception of a Rose

When I smell a rose, there is in this operation both sensation and perception. The agreeable odor I feel, considered by itself without relation to any external object, is merely a sensation. It affects the mind in a certain way; and this affection of the mind may be conceived without a thought of the rose, or any other object. This sensation can be nothing else than it is felt to be. Its very essence consists in being felt, and, when it is not felt, it is not. There is no difference between t...

 "The primitive Christians condemn pleasure and luxury"

The acquisition of knowledge, the exercise of our reason or fancy, and the cheerful flow of unguarded conversation, may employ the leisure of a liberal mind. Such amusements, however, were rejected with abhorrence, or admitted with the utmost caution, by the severity of the fathers, who despised all knowledge that was not useful to salvation, and who considered all levity of discourse as a criminal abuse of the gift of speech. In our present state of existence the body is so inseparably conne...

 Infective Hallucination in "Martian Chronicles"

The psychologist shut his eyes and scratched his nose. “This is the most incredible example of sensual hallucination and hypnotic suggestion I’ve ever encountered. I went through your «rocket,» as you call it.” He tapped the hull. “I hear it. Auditory fantasy.” He drew a breath. “I smell it. Olfactory hallucination, induced by sensual telepathy.” He kissed the ship. “I taste it. Labial fantasy!” He shook the captain’s hand. “May I congratulate you? You are a psychotic...

 The Other Men

This planet, being essentially of the terrestrial type, had produced a race that was essentially human, though, so to speak, human in a different key from the terrestrial. These continents were as variegated as ours, and inhabited by a race as diversified as Homo sapiens. All the modes and facets of the spirit manifested in our history had their equivalents in the history of the Other Men. As with us, there had been dark ages and ages of brilliance, phases of advancement and of retreat, cultu...

 The Receiving Set

In radio and television, for instance, the Other Men were technically far ahead of us, but the use to which they put their astounding inventions was disastrous. In civilized countries everyone but the pariahs carried a pocket receiving set. As the Other Men had no music, this may seem odd; but since they lacked newspapers, radio was the only means by which the man in the street could learn the lottery and sporting results which were his staple mental diet. The place of music, moreover, was ta...

 Religion on Other Earth

Perhaps the most striking example of the extravagance of the Other Men was the part played by religion in their more advanced societies. Religion was a much greater power than on my own planet; and the religious teachings of the prophets of old were able to kindle even my alien and sluggish heart with fervor. Yet religion, as it occurred around me in contemporary society, was far from edifying. I must begin by explaining that in the development of religion on the Other Earth gustatory sensat...

 Scent on an Airless Planet

Scent seems to have all the disadvantages and none of the advantages, as a long-range sense. However, under special circumstances even a modified nose may fill the need. In a story of my own some years ago ("Uncommon Sense," Astounding Science Fiction, September 1945), I assumed an airless planet, so that molecules could diffuse in nearly straight lines. The local sense organs were basically pinhole cameras, with the retinal mosaic formed of olfactory cells. Since the beings in question were ...
