 Added 17 Oct 1814. Quere whether to add these to the list of separate rules?

Ought not this to be applied to the assistance and direction of the judgment? See Ch. Methodization under that head:

Rule. In taking a survey of practice, distinguish in it as many distinguishable points as the nature of the case appears to afford, and on each of those points, try its utility and propriety by its relation to the end.

Examples. The field of medical practice is a field in which many examples indicative of the utility of this rule might be collected. In the comparatively antient system of pharmacy may be found medicines in the composition of which drugs to the amount of twenty or thirty different sorts, of which, by comparatively recent observation, experience and experiment all but two or three have been found either wholly inoperative or unconducive to the end.

In every part of the field, in which the practice has not yet been thus dissected, and its several distinguishable parts or points[?] confronted with the proper end, uninfluencing circumstances and even obstructive circumstances, i.e. obstacles, may be seen confounded with promotive causes, and the result be it what it may, ascribed without distinction to their conjunct agency: and, in this way, the character of promotive causes ascribed to uninfluencing and even to obstructive causes.

Of this mode of confusion, examples will naturally be to be found in abundance in the system of government established in every country, and in particular in that branch which regards constitutional law. Of whatsoever measure of prosperity the state may be supposed to be in the enjoyment of, as many abuses and imperfections as by the theory or practice of it have place, will by all those who profit by them, be of course placed more or less confidently and explicitly upon the list of promotive causes.

See the work on Fallacies.

    In relation to the result in question, considered in the character of an effect, suppose, at pleasure, any one body to be the prime or principal mover or agent, and the motion, the action, or the operation of it, to be the prime or principal cause.

    In no instance can any such cause be in operation, but it will happen to it to be, on all sides, encompassed and surrounded by circumstances.

    Those circumstances will be composed /consist/ of the state of the contiguous and surrounding bodies, in respect of motion or rest, form, colour, quantity, and the like.

    Among these some will appear to be exercising on the result a material operative influence: others not to be exercising such influence. Influential and influencing circumstances, uninfluential or uninfluencing circumstances; in one or other of these two classes of circumstances, taken together, will every circumstance by which it can happen to the principal agent or agents to be encompassed, be comprised /referred/.

    Promotive or obstructive - under one or other of these denominations may the whole assemblage of influential circumstances be comprised.

    Any circumstances that operate /act/ that are considered as acting /operating/ in the character of obstructive circumstances are termed in one word obstacles.

    Prone as is the human mind to the making of hasty and incompletely /imperfectly/-grounded inductions in /on/ the field of physics /physical science/, it can not but be much more so in the fields of psychology and ethics, in which is included the field of politics: commonly not only is the collection made of influencing circumstances incomplete, but uninfluencing circumstances, and even obstacles, are placed in the station of, and held up to view in the character of, principally or even exclusively operating causes.

    Thus superior is the density of the clouds which overhang the relation between cause and effect in the field of morals, as compared with the field of physics. Two concurring considerations may help us to account for this difference, - 1. The elements of calculation being in so large a proportion of the psychical class - such as intentions, affections, and motives, - are, in a proportional degree, situated out of the reach of direct observation. 2. In the making of the calculation, the judgment is, in a peculiar degree, liable to be disturbed and led astray by the several sources of illusion, - by original intellectual weakness, by sinister interest, by interest-begotten prejudice, and by adopted prejudice.

    Object accordingly at every step to cover the whole field, as a pond or stream is endeavoured to be covered with dragnets; to cover the whole of the ground [...?] of which covered by Aristotle, Bacon and Locke

    As to its field or subject - the subject on which its operations are performed - it is neither more nor less than the entire field of human thought and action. In it is included /accordingly/ the whole field of art and /science and/ science: in it is moreover included the field of ordinary i.e. unscientific thought and ordinary i.e. unartificial action or say practice: together with /including/ the whole contents of these /that/ respective fields /field/: viz. all the subjects not only of human action but of human thought. all entities not only real but fictitious not only all real entities, but all fictitious ones that have ever been feigned, or remain capable of being feigned: fictitious entities - those necessary products /points/ of the imagination without which fictitious /unreal/ as they are, language could not - scarcely could even thought, be carried on: and which, by being embodied as it were in a name /in names/, and thus put upon a footing with real ones, have been /are/ so apt to be mistaken for real ones. Thus in one or other of these two divisions the whole field of human thought and action is included /comprehended/.

    21 Sept. 1814. Logic which has for the object of its exercize and endeavours the the [sic] rational faculty is the art of applying reason with the utmost possible advantage to all the subjects to which it is capable of being applied of being made to apply itself.

    On the one hand, artificial action or practice and scientific thought - on the other hand ordinary /trivial/ or inartificial practice and ordinary /trivial/ or unscientific thought and ordinary /trivial/ and inartificial practice - under these two divisions taken together the whole field of human thought as well as the whole field of human action can not, it is evident fail of being comprehended /concluded/.
