How do rational minds make contact with the world? The empiricist tradition sees a gap between mind and world, and takes sensory experience, fallible as it is, to provide our only bridge across that gap. In its crudest form, for example, the traditional idea is that our minds consult an inner realm of sensory experience, which provides us with evidence about the nature of external reality. Notoriously, however, it turns out to be far from clear that there is any viable (...) conception of experience which allows it to do the job. The original problem is to show that thought is rationally constrained by external reality. If sensory experience is to provide the solution--in particular, if it is to provide the answer to sceptical challenges--it must therefore meet two criteria. First, it must itself be `receptive'--i.e., appropriately constrained by external reality. Second, it must be the kind of thing that can enter into a logical or rational relationship with belief--it must already be `conceptual,' in other words. In arguing against the idea that anything could serve both roles, Wilfred Sellars termed this conception of experience "the Myth of the Given.". (shrink)

In this paper I explore a justification for transcendental idealism that emerges from the dialogue with philosophical scepticism in which Kant is on and off engaged throughout the Critique of Pure Reason. Many commentators, most prominently Strawson, have claimed that transcend‐ ental idealism is an unfortunate addition to the Critique, one that can profitably be excised in the interests of clarity and coherence. Against this general picture I urge that transcendental idealism is in fact a very natural consequence of some (...) of the central doctrines of the Critical Philosophy. It is in the context of Kant's debate with scepticism that this emerges most clearly. Nonetheless, I argue that Kant's employment of transcendental idealism against the sceptic is seriously compromised by his postulating the existence of unknowable things‐in‐themselves. As long as he maintains that there are unknowable things‐in‐themselves which are responsible for our having the experience that we do have, his position seems to collapse into sceptical idealism. In the final section of the paper I suggest that the only possible escape from this difficulty would be to rule out the possibility of affirming that unknowable things‐in‐themselves exist. I also suggest that an argument to this effect exists in the Critique and that Kant's position would be more consistent had he adhered to it. (shrink)

Much as we would like to conceive empirical thought as rationally grounded in experience, pitfalls await anyone who tries to articulate this position, and ...

Tractatus, 5.62 famously says: ‘… what the solipsist means is quite correct; only it cannot be said but makes itself manifest. The world is my world: this is manifest in the fact that the limits of language mean the limits of my world.’ The later part of this repeats what was said in summary at 5.6: ‘the limits of my language mean the limits of my world’. And the key to the problem ‘how much truth there is in solipsism’ has (...) been provided by the reflections of TLP, 5.61. (shrink)
