Daniel Dennett quotes - page 2
We alone can be wracked with doubt, and we alone have been provoked by that epistemic itch to seek a remedy: better truth-seeking methods. Wanting to keep better track of our food supplies, our territories, our families, our enemies, we discovered the benefits of talking it over with others, asking questions, passing on lore. We invented culture. Then we invented measuring, and arithmetic, and maps, and writing. These communicative and recording innovations come with a built-in ideal: truth. The point of asking questions is to find true answers; the point of measuring is to measure accurately; the point of making maps is to find your way to your destination. ... In short, the goal of truth goes without saying, in every human culture.
Daniel Dennett
Evolution is all about processes that almost never happen. Every birth in every lineage is a potential speciation event, but speciation almost never happens, not once in a million births. Mutation in DNA almost never happens - not once in a trillion copings - but evolution depends on it. Take the set of infrequent accidents - things that almost never happen - and sort them into the happy accidents, the neutral accidents, and the fatal accidents; amplify the effects of the happy accidents - which happens automatically when you have replication and competition - and you get evolution.

There is a familiar trio of reactions by scientists to a purportedly radical hypothesis: (a) "You must be out of your mind!", (b) "What else is new? Everybody knows that!", and, later - if the hypothesis is still standing - (c) "Hmm. You *might* be on to something!" Sometimes these phases take years to unfold, one after another, but I have seen all three emerge in near synchrony in the course of a half-hour's heated discussion following a conference paper.
Daniel Dennett
Of all the mind tools we acquire in the course of furnishing our brains from the stockpiles of culture, none are more important, of course, than words - first spoken, then written. Words make us more intelligent by making cognition easier, in the same way (many times multiplied) that beacons and landmarks make navigation in the world easier for simple creatures. Navigation in the abstract multidimensional world of ideas is simply impossible without a huge stock of movable, memorable landmarks that can be shared, criticized, recorded, and looked at from different perspectives.

The salmon swimming upstream to spawn may be wily in a hundred ways, but she cannot even contemplate the prospect of abandoning her reproductive project and deciding instead to live out her days studying coastal geography or trying to learn Portuguese. The creation of a panoply of new standpoints is, to my mind, the most striking product of the euprimatic revolution.
Daniel Dennett
Up till now [the development of proto-consciousness], we can suppose, nervous systems solved the "Now what do I do?" problem by a relatively simple balancing act between a strictly limited repertoire of actions - if not the famous four F's (fight, flee, feed, or mate), then a modest elaboration of them.
Daniel Dennett
In spite of ferocious differences of opinion about other moral issues, there seems to be something approaching consensus that it is cruel and malicious to interfere with the life-enhancing illusions of others -unless those illusions are themselves the cause of of even greater ills. The disagreements come over what these greater ills might be- and this has led to the break down of the whole rationale. Keeping secrets from people for their own good can often be wise, but it takes only one person to give away a secret, and since there are disagreements about which cases warrant discretion, the result is an unsavory miasma of hypocrisy, lies, and frantic but fruitless attempts at distraction.
Daniel Dennett
[I]t makes little difference where we draw the line between the pruning and shaping [of behavior] by natural selection which is genetically transmitted to offspring (the wiring you are born with), and the pruning and shaping that later takes place in the individual (the rewiring you end up with, as a result of experience or training). Nature and nurture blend seamlessly together.
