I am very suspicious of claiming that morality implies "intrinsic value" to the pursuit of truth. I am not really sure whether or not "intrinsic value" actually exists. It would seem to me that whatever the reasons one has for pursuing truth about a certain topic of discovery is reason enough and we need not posit mysterious words like "intrinsic value". The moral justification for pursuing truth would be that knowlege leads to truth belief which lead to good intentions and actions and the world is far better off if people are acting on true beliefs, therefore we have good reasons to be truth-seekers.
