Slipping on the Slippery Slope Argument By Chris Knight (Florida)

The slippery slope argument has been employed in many areas of public policy, but is widely rejected by professional philosophers, which is a mighty good reason for thinking that the argument has merits. The idea is to take some position, and through steps accepted to the holder, show that absurd conclusions, or at least conclusions inconsistent with the position of the opponent follow. For example, the liberal philosophy of “thou shall not discriminate,” leads to ultimately accepting animal rights, and with some argument, plant rights as well, as recent evidence indicates plants may have proto-mental qualities. Likewise, arguments for abortion seem to fall into infanticide, which is exactly what we are seeing. Thus, the slippery slope argument is a valuable tool for showing the absurdity of the ideologies of the present regime.

“Every now and then, a piece of philosophical theory breaks into the popular consciousness, such that people without any philosophical education regularly refer to it. One such theory is the rejection of the slippery-slope argument, which holds that an event, A, will set off a series of events culminating in some dreadful consequence, B—and therefore A should not occur. “The supposed ‘slippery slopes’ are fake, silly rhetoric to placate the faithful,” a columnist recently wrote, pointing to how partisans on different sides of contentious issues like gun rights or abortion take extreme positions. True, such arguments can sometimes ignore a potential middle ground and overlook the fact that the dreaded consequence will not necessarily follow. But slippery-slope arguments are not always incorrect, and they offer insight about the nature of modern progressivism.

Usually, rejection of slippery-slope arguments occurs in the context of their claims that some policy will have bad consequences. These claims may be wrong, but the slippery-slope label does not prove their wrongness. Societies slide down such slopes all the time: history is full of examples of nations that moved in a progressive direction over time, tended toward decadence or exhaustion after altering rules for elites, and then relaxed moral standards. Indeed, the slippery-slope argument, especially in the context of social decay, has a noble pedigree. Plato observes in The Republic that democracy leads to authoritarianism; as freedom and equality expand beyond orderly limits, only hardheaded authority can rein them in. The fall of the Roman republic to authoritarian empire and the rapid collapse of French republicanism before the rise of Napoleon stand as examples.

Today’s slippery slopes are more familiar. Consider contemporary discussion over the nature of rights. While political conservatives generally define rights negatively (freedom from something), progressives define them positively (freedom to something). The preservation of negative liberties is definite and circumscribed, seeking to conserve a particular thing; the search for positive liberties is less bounded, aiming to widen the scope of what is alleged to be true freedom. Contemporary progressives tend not to be satisfied with certain political victories, which, once achieved, give way to new demands: for example, activists hoping to secure rights for sexual minorities initially made assurances that those who disagreed would be left alone; now they intend to stamp out dissent and expand the universe of rights beyond gay marriage. Given this history, one may be forgiven for suspicion of progressive intentions, or for concluding that the slippery slope is itself embedded in the progressive posture. It is also a definitional question. Whereas conservatism wishes to remain in one place, or, at most, to move only in certain limited respects, the very definition of progressivism is to progress—that is, to keep moving.

But the slippery-slope argument often resonates as a criticism of modern progressivism and liberalism. By leaving the space open for debate and increased equality, liberalism tends to empower those who, unwittingly or not, seek to overthrow anything that can be called liberal. The race to ever-changing equality takes on a logic of its own. The slippery-slope argument is therefore plausibly applicable to progressive politics, by dint of the latter’s own nature to push onward.

Slippery-slope arguments thus deserve some respect. The mere fact that an argument follows that form is largely irrelevant to determining its veracity. Someone accused by his interlocutor of using the slippery-slope argument should reply that the debate should not focus on the notion that cause A could lead to cause B—which is unremarkable—but rather, on how likely it is that cause A could lead to cause B. If recent experience is any indication, the slippery slope against which that interlocutor had protested is likely to unfold in all its decadence as the years progress.”
