“What is called "objectivity," scientific for instance (in which I firmly believe, in a given situation) imposes itself only within a context which is extremely vast, old, firmly established, or rooted in a network of conventions … and yet which still remains a context.”

“What we firmly believe, if it is true, is called knowledge, provided it is either intuitive or inferred (logically or psychologically) from intuitive knowledge from which it follows logically. What we firmly believe, if it is not true, is called error. What we firmly believe, if it is neither knowledge nor error, and also what we believe hesitatingly, because it is, or is derived from, something which has not the highest degree of self-evidence, may be called probable opinion. Thus the greater part of what would commonly pass as knowledge is more or less probable opinion.”

“Nothing is so firmly believed as that which is least known.”

“We rely on faith only in the context of claims for which there is no sufficient sensory or logical evidence.”

“Freedom can only be understood in the context of destiny, or those things which limit our freedom.”

“Argumentation is a human enterprise that is embedded in a larger social and psychological context. This context includes (1) the total psyches of the two persons engaged in dialogue, (2) the relationship between the two persons, (3) the immediate situation in which they find themselves and (4) the larger social, cultural and historical situation surrounding them.”
