{{cquote|It is not at all necessarily the same to be certain of something as it is to regard something as being true. There are all sorts of things--matters of fact or feeling or action--about which we may be certain although they may not be judged either true or false. That is mainly because our judgements about them are contingent upon our experience and present circumstance, while true propositions are those that we expect to hold in all circumstances.}}
