Rand’s Problem with the Problem of Induction

Dykes:

By careful observation – free from preconception – we are able to discover the identities of the entities we observe. Thereafter, we are fully entitled to assume that like entities will cause like events, the form of inference we call induction. And, because it rests on the axiom of the Law of Identity, correct induction – free from contradiction – is a valid route to knowledge. (¶ 11)

I must address this paragraph, line by line: “By careful observation – free from preconception – we are able to discover the identities of the entities we observe.” (¶ 11) The assumption that we may have unmediated observation, ‘free from preconception’, is just that: an assumption that such an observation may take place. From what we know in neuroscience and basic biology, it appears that all sensory qualities we have are not in any way immediate. It is dubious, to say the least, that it is possible to observe ‘free from preconception’, for it would require a mind wiped clean even of its structure, and perhaps eliminating all its previous content. Simply put, the mind is not in any way a blank slate. To counter the fact that it is impossible to know if one is observing ‘free from preconception’ by declaring that we have observation ‘free from preconception’ is absurd.

Thus, Dykes must first argue that observation is ‘free from preconception,’ and that we may come to know which observations are ‘free from preconception’ and which observations are not.
