Quote:Let us begin with a parable. It is a parable developed from a tale told by John Wisdom in his haunting and revelatory article 'Gods'.[1] Once upon a time two explorers came upon a clearing in the jungle. In the clearing were growing many flowers and many weeds. One explorer says, "some gardener must tend this plot." The other disagrees, "There is no gardener." So they pitch their tents and set a watch. No gardener is ever seen. "But perhaps he is an invisible gardener." So they, set up a barbed-wire fence. They electrify it. They patrol with bloodhounds. (For they remember how H.G. Wells's The Invisible Mancould be both smelt and touched though he could not he seen.) But no shrieks ever suggest that some intruder has received a shock. No movements of the wire ever betray an invisible climber. The bloodhounds never give cry. Yet still the Believer is not convinced. "But there is a gardener, invisible, intangible, insensible to electric shocks, a gardener who has no scent and makes no sound, a gardener who comes secretly to look after the garden which he loves." At last the Sceptic despairs, "But what remains of your original assertion? Just how does what you call an invisible, intangible, eternally elusive gardener differ from an imaginary gardener or even from no gardener at all?"
In this parable we can see how what starts as an assertion that something exists or that there is some analogy between certain complexes of phenomena, may be reduced step by step to an altogether different status, to an expression perhaps of a 'picture preference'.[2] The Sceptic says there is no gardener. The Believer says there is a gardener (but invisible, etc.) One man talks about sexual behaviour. Another man prefers to talk of Aphrodite (but knows that there is not really a superhuman person additional to, and somehow responsible for, all sexual phenomena).[3] The process of qualification may be checked at any point before the original assertion is completely withdrawn and something of that first assertion will remain (Tautology). Mr. Wells's invisible man could not, admittedly, be seen, but in all other respects he was a man like the rest of us. But though the process of qualification may be, and of course usually is, checked in time, it is not always judiciously so halted. Someone may dissipate his assertion completely without noticing that he has done so. A fine brash hypothesis may thus be killed by inches, the death by a thousand qualifications.
