Meeting of the minds
Concept in academic work

In the law of contract the use of moral phraseology led to equal confusion, as I have shown in part already, but only in part. Morals deal with the actual internal state of the individual's mind, what he actually intends. From the time of the Romans down to now, this mode of dealing has affected the language of the law as to contract, and the language used has reacted upon the thought. We talk about a contract as a meeting of the minds of the parties, and thence it is inferred in various cases that there is no contract because their minds have not met; that is, because they have intended different things or because one party has not known of the assent of the other. Yet nothing is more certain than that parties may be bound by a contract to things which neither of them intended, and when one does not know of the other's assent. Suppose a contract is executed in due form and in writing to deliver a lecture, mentioning no time. One of the parties thinks that the promise will be construed to mean at once, within a week. The other thinks that it means when he is ready. The court says that it means within a reasonable time. The parties are bound by the contract as it is interpreted by the court, yet neither of them meant what the court declares that they have said. In my opinion no one will understand the true theory of contract or be able even to discuss some fundamental questions intelligently until he has understood that all contracts are formal, that the making of a contract depends not on the agreement of two minds in one intention, but on the agreement of two sets of external signs — not on the parties' having meant the same thing but on their having said the same thing.
