Seldom do man realise that attempt to eradicate certain species, would trigger more dreadful evolution that put forth highly resistant and stronger variations of that beings. According to Palumbi, one such example was the discovery of DDT a mile stone in revolution against pest that won Paul Muller the 1948 Nobel Prize, but astoundingly, resistant variants of insects that could survive DDT were found even before the Nobel Ceremony took place.

Wittgenstein’s is an explanation that compounds and merely ‘adds on’ the notion or idea of an explanation, and in Black’s analogy, this amounts to a tautology at best, and at worst, a circular argument – e.g. stamps stick to envelopes, because other stamps stick to envelopes. The following will examine the 'picture theory' of language and how it relates tautologically or as a 'self contradiction'.
