Abstract

We propose a simple ontological law for the consumer age: if a product can be imagined, it already exists. The result is stated as Theorem 1 and proved in a single line. Supporting evidence is published daily, one corollary at a time. The principle is summarised as follows.

“I imagined it, therefore it exists.”

Keywords: ontology, imagination, obscure products, retail, existence proofs

1Introduction

In 1637 Descartes inferred his own existence from the act of thinking [1]. The present work extends his result, modestly, to everything else. It rests on one repeatable observation: whenever a sufficiently specific and sufficiently absurd product is imagined, a brief search reveals that someone, somewhere, is already selling it.

We formalise this observation below and invite the reader to attempt a counterexample. None has yet survived peer review.

Theorem 1

Theorem 1 (The Linkola Principle). For every product x, if x can be imagined, then x exists.

∀x :  𝓘(x)  ⇒  ∃x(1)

Proof. I imagined it.∎

Figure 1: The ontological transition. A dashed outline denotes an object that has merely been imagined; a solid outline denotes the same object, existing. By Theorem 1 the arrow is instantaneous.

2Empirical Evidence

Each day the author imagines one new product and publishes the resulting corollary. A selection is reproduced in Table 1.

3Peer Review

Readers may submit conjectures of their own. Accepted submissions are published as corollaries, with credit to the imaginer.

4Limitations

The author has not yet imagined any.
