A Quote by David Hume

To consider the matter aright, reason is nothing but a wonderful and unintelligible instinct in our souls, which carries us along a certain train of ideas, and endows them with particular qualities, according to their particular situations and relations. This instinct, 'tis true, arises from past observation and experience; but can anyone give the ultimate reason, why past experience and observation produces such an effect, any more than why nature alone should produce it?
...I believe there exists, & I feel within me, an instinct for the truth, or knowledge or discovery, of something of the same nature as the instinct of virtue, & that our having such an instinct is reason enough for scientific researches without any practical results ever ensuing from them.
There are established processes of consultation between the Government, the parastatals and the trade unions, which have worked in the past. And I don't see any particular reason why they shouldn't work.
Whereas certain people start with a recollection or an experience and paint that experience, to some of us the act of doing is the experience; so that we are not quite clear why we are engaged on a particular work. And because we are more interested in plastic matters than we are in matters of words, once can begin a painting and carry it through and stop it and do nothing about the title at all. All pictures are full of association.
The forming of general maxims from particular observation is a very nice operation; and nothing is more usual, from haste or a narrowness of mind, which sees not on all sides, than to commit mistakes in this particular.
Why, thou knowest I am as valiant as Hercules, but beware instinct. The lion will not touch the true prince. Instinct is a great matter. I was a coward on instinct.
There is no good reason why we should fear the future, but there is every reason why we should face it seriously, neither hiding from ourselves the gravity of the problems before us nor fearing to approach these problems with the unbending, unflinching purpose to solve them aright.
With the unknown, one is confronted with danger, discomfort, and care; the first instinct is to abolish these painful states. First principle: any explanation is better than none. . . . The causal instinct is thus conditional upon, and excited by, the feeling of fear. The "why?" shall, if at all possible, not give the cause for its own sake so much as for a particular kind of cause -- a cause that is comforting, liberating, and relieving.
The philosophical question before us is, when we make an observation of our track in the past, does the result of our observation become real in the same sense that the final state would be defined if an outside observer were to make the observation?
We know nothing of the principle of health, the positive of which pathology is the negative, except from observation and experience. Nothing but observation and experience will teach us the ways to maintain or to bring back the state of health. It is often thought that medicine is the curative process. It is no such thing; medicine is the surgery of functions as surgery proper is that of limbs and organs.
A man's knowledge may be said to be mature, in other words, when it has reached the most complete state of perfection to which he, as an individual, is capable of bringing it, when an exact correspondence is established between the whole of his abstract ideas and the things he has actually perceived for himself. His will mean that each of his abstract ideas rests, directly or indirectly, upon a basis of observation, which alone endows it with any real value; and also that he is able to place every observation he makes under the right abstract idea which belongs to it.
We have three approaches at our disposal: the observation of nature, reflection, and experimentation. Observation serves to assemble the data, reflection to synthesise them and experimentation to test the results of the synthesis. The observation of nature must be assiduous, just as reflection must be profound, and experimentation accurate. These three approaches are rarely found together, which explains why creative geniuses are so rare.
All our knowledge hast its origins in our perceptions … In nature there is no effect without a cause … Experience never errs; it is only your judgments that err by promising themselves effects such as are not caused by your experiments … Science is the observation of things possible, whether present or past; prescience is the knowledge of things which may come to pass.
When a rainbow appears vividly in the sky, you can see its beautiful colors, yet you could not wear as clothing or put it on as an ornament. It arises through the conjunction of various factors, but there is nothing about it that can be grasped. Likewise, thoughts that arise in the mind have no tangible existence or intrinsic solidity. There is no logical reason why thoughts, which have no substance, should have so much power over you, nor is there any reason why you should become their slave.
Even after the observation of the frequent conjunction of objects, we have no reason to draw any inference concerning any object beyond those of which we have had experience.
There is no reason why EPA's role should ebb and flow based on a particular administration or a particular administrator.
Nature has willed that man should, by himself, produce everything that goes beyond the mechanical ordering of his animal existence, and that he should partake of no other happiness or perfection than that which he himself, independently of instinct, has created by his own reason.
