It is common, though perhaps not correct, to think that practical rationality is strictly instrumental.1 The functions of instrumental reason include finding suitable means to our determinate ends, helping to determine our indeterminate ends, and implementing our principles in appropriate actions. One reason that might be given for adopting instrumentalism with respect to rationality might be that our best scientific evidence offers little support for the idea that our brains have powers to detect good and bad as such in persons, actions, or lives. But whatever one’s reasons for taking up instrumentalism, it remains to specify the relationship means are to have with ends. A natural demand is that instrumentally rational actions implement the best means to one’s given ends. Optimizing conceptions of rationality endorse this demand. A competing conception of rationality—the satisficing conception—weakens this requirement and permits some rational actions to implement (merely) satisfactory means to the agent’s given ends. The present article argues that instrumentalist theories of rationality as commonly understood cannot consistently accommodate this satisficing conception of rationality.

Aquinas accepts that (i) some kinds of voluntary action are (qua voluntary) “basic,” not divisible into (non-fictional) further kinds; (ii) a concrete individual action may belong to more than one basic kind; (iii) the basic kinds to which it belongs are determined by the agent’s intentions qua performing the action; (iv) some intentions may stand to others as means to ends; (v) there can be concrete individual actions in which the agent’s intended means are disordered with respect to the ends; (vi) such actions are morally wrong; (vii) whether a given intention is disordered as means to a given end is determined solely by the natures of the agent and of the intended means or ends. Together, these propositions entail that, pace many analytic philosophers, concrete individual actions can have a moral wrongness that consists neither in expectation of disutility nor in violation of the pure logic of practical reason.

The question of what means-and-ends structure our epistemic endeavors have is an important issue in recent epistemology, and is fundamental for understanding epistemic matters in principle. Crispin Sartwell has proposed arguments for the view that knowledge is our only ultimate goal, and justification is no part of it. An important argument is his instrumentality argument which is concerned with the conditions under which something could belong to our ultimate epistemic goal. Recently, this argument has been reconstructed and criticized by Pierre Le Morvan in a clear and helpful way. It will be shown, however, that Le Morvan’s criticism is not adequate, since it misconstrues the real instrumentality argument that can be found in Sartwell’s writings.

This essay offers a start on sorting out the relationships of argumentation and persuasion by identifying two systematic ways in which definitions of argumentation differ, namely, their descriptions of the ends and of the means involved in argumentative discourse. Against that backdrop, the traditional “conviction-persuasion” distinction is reassessed. The essay argues that the traditional distinction correctly recognizes the difference between the end of influencing attitudes and that of influencing behavior—but that it misanalyzes the means of achieving the latter (by focusing on emotional arousal) and that it mistakenly contrasts “rational” and “emotional” means of influence. The larger conclusion is that understanding the relationships of the phenomena of argumentation and persuasion will require close attention to characterizations of communicative ends and means.

Goal-directed problem solving as originally advocated by Herbert Simon’s means-ends analysis model has primarily shaped the course of design research on artificially intelligent systems for problem-solving. We contend that there is a definite disregard of a key phase within the overall design process that in fact logically precedes the actual problem solving phase. While systems designers have traditionally been obsessed with goal-directed problem solving, the basic determinants of the ultimate desired goal state still remain to be fully understood or categorically defined. We propose a rational framework built on a set of logically inter-connected conjectures to specifically recognize this neglected phase in the overall design process of intelligent systems for practical problem-solving applications.

The illusory appeal of double effect -- The significance of intent -- Means and ends -- Blame.

applies to a single, unified agent (either an individual or corporate person) with the powers of judgment and deliberation in seeking ends and interests peculiarly its own. The rational applies to how these ends and interests are adopted and affirmed, as well as to how they are given priority. It also applies to the choice of means, in which case it is guided by such familiar principles as: to adopt the most effective means to ends, or to select the more probable alternative, other things equal….

This paper describes the corner-stones of a means-ends approach to the philosophy of inductive inference. I begin with a fallibilist ideal of convergence to the truth in the long run, or in the 'limit of inquiry'. I determine which methods are optimal for attaining additional epistemic aims (notably fast and steady convergence to the truth). Means-ends vindications of (a version of) Occam's Razor and the natural generalizations in a Goodmanian Riddle of Induction illustrate the power of this approach. The paper establishes a hierarchy of means-ends notions of empirical success, and discusses a number of issues, results and applications of means-ends epistemology.
