Reading Group: Derrida's Voice and Phenomenon (This summary is pretty rough and leaves a few things out, but just to at least get things started:)
Chapter 2 continues the close reading of Husserl’s first logical investigation. It covers sections 2-4 of the investigation, those sections in which Husserl concentrates on indication.
Before attending directly to the text, Derrida considers why indication is given such short shrift (having less than one third as many sections devoted to it as expression.) He surmises, as he will surmise often, that Husserl views indication as a phenomenon of secondary importance, as something extrinsic to expression. If indication is introduced first, it’s only to hastily, preemptively quarantine it, so that we can go on to explore expression unimpeded.
Derrida then turns to Husserl’s text.
First Husserl introduces another distinction, this time within indication. There is natural indication and there is artificial indication. Natural indication is something like: “where there’s smoke, there’s fire.” Here, indicators are intrinsically linked to what they indicate. Artificial indications, on the other hand, rely on convention, as in the case of branding.
Both natural and artificial indication, though, share something essential. In both cases something we currently know (that which functions as an indicator) motivates our conviction in (or presumption of) something we don’t yet know (that which is indicated.)
Derrida quotes Husserl’s definition in full & I think it’s worth requoting here:
“In these cases we discover as a common characteristic the following situation: certain objects or states of affairs whatsoever whose subsistence of what someone has actual knowledge indicate to him the subsistence of certain other objects or states of affairs, in the sense that his conviction in the being of the one is experienced as motivating (though as a non-evident motivation) a conviction or a presumption in the being of the others. “
Unfortunately this definition casts a bit too wide of a net. While it does cover indication in the sense we’ve been discussing (Anweis) it would also include deductive, apodictic demonstrations or proofs (Hisweis.) These latter have for their content universal, necessarily valid truths. Instead of something merely ‘indicating’ something else, with 'Hinweis, it logically/mathematically entails it. For instance, if we know, of a square, that its sides are four feet long, we are, as with indication, ‘motivated’ to pass from this knowledge to the knowledge that the square has an area of 16 square feet. Yet the square’s area is, in a sense, already implicit in the length of its sides.
The difference is that, while 'hinweis' is apodictic, 'anweis' is always a matter of empirical probability. The existence of A strongly, perhaps even overwhelmingly, suggests the existence of B, yet this can never be more than an empirical near-certainty.
Yet even within Hinweis, Husserl draws a distinction between the factual experiential ‘acts’ of deducing one thing from another and the ideal/objective relations which are the contents of those deductions This, to Derrida, suggests an indicative component even within the heart of (factual) demonstration (of objective truths.)
Derrida seizes upon this distinction as on opportunity to change gear, shifting from commentary on the text to its implications for the phenomenological project in general. Derrida sees in this distinction yet another instance of a move Husserl will constantly repeat. In order to secure the integrity of one thing, something else is relegated as being essentially exterior to it. All of phenomenology, he claims, boils down to making distinctions between the essential and the inessential. But the ability to make these kinds of distinctions is, itself, a function of language.
But, says Derrida, Husserl clearly would not himself characterize phenomenology in this way. After all, Husserl holds that there is a pre-linguistic stratum of sense.
