It is for shortness' sake that the proposition is stated as it stands in the text. If critically examined, it might be found, perhaps, to be scarcely justifiable by the laws of language. For the fictitious entities, characterised by the two abstract terms, trust and condition, are not subalternate but disparate. To speak with perfect precision, we should say that he who is invested with a trust is, on that account, spoken of as being invested with a condition: viz. the condition of a trustee. We speak of the condition of a trustee as we speak of the condition of a husband or a father.
