Vasubandhu’s arguments against atomism in Viṃśikā stanzas 12–13 are not strong enough to disprove that atoms are simple partless substances. However, if we take the special composition question into consideration, Viṃśikā stanza 13ab can be regarded as an objection to so-called series-style answers, which results in an undesirable conclusion for the opponents, i.e. the Vaibhāṣikas. A step back to a simple bonding answer is not a good choice for the Vaibhāṣikas in responding to this objection because the simple bonding answer (...) leads to other difficulties and because some notions in Vaibhāṣika atomic theory entail multigrade relations in the material aggregates of atoms. Hence, the objection to series-style answers still makes sense in the refutation of Buddhist atomism through the claim that atoms are not proper parts of a material aggregate. (shrink)
