The 9 ideas from 'Tarski's Theory of Truth'

Tarski reduced truth to reference or denotation [Field,H, by Hart,WD]
Tarski really explained truth in terms of denoting, predicating and satisfied functions [Field,H]
Field says reference is a causal physical relation between mental states and objects [Field,H, by Putnam]
Tarski just reduced truth to some other undefined semantic notions [Field,H]
Tarski gives us the account of truth needed to build a group of true sentences in a model [Field,H]
In the early 1930s many philosophers thought truth was not scientific [Field,H]
The notion of truth is to help us make use of the utterances of others [Field,H]
'Valence' and 'gene' had to be reduced to show their compatibility with physicalism [Field,H]
Model theory is unusual in restricting the range of the quantifiers [Field,H]
