Belief, disbelief; agreement, disagreement
In a recent PLOS ONE paper, we conducted an evidence-based analysis of current versus historical fire regimes and concluded that traditionally defined reference conditions of low-severity fire regimes for ponderosa pine Pinus ponderosa and mixed-conifer forests were incomplete, missing considerable variability in forest structure and fire regimes.
Stevens et al. Here we highlight areas of agreement and disagreement about past fire, and analyze the methods Stevens et al. We found a major problem with a calculation they used to conclude that the FIA data were not useful for evaluating fire regimes. Their calculation, as well as a narrowing of the definition of high-severity fire from the one we used, leads to a large underestimate of conditions consistent with historical high-severity fire.
The FIA stand age data do have limitations but they are consistent with other landscape-inference data sources in supporting a broader paradigm about historical variability of fire in ponderosa and mixed-conifer forests than had been traditionally recognized, as described in our previous PLOS paper.

The accompanying paper by Stevens et al. Specifically, Stevens et al. Here, we first briefly summarize points of agreement between Stevens et al. Authorship of this reply is comprised by those who conducted the FIA portion of Odion et al. In Odion et al. Over three-quarters of our results pertained to lines of evidence other than FIA stand age data. We did not intend to suggest that tree recruitment occurred only with fire. We agree that this process occurred historically. There is also agreement that a dominant cohort of trees will establish after high-severity fire, but that later in stand development understory recruitment can happen with favorable climate or following insect outbreaks.
This, along with the presence of some trees that pre-date the fire, will create an uneven-aged stand, but there may still be a dominant overstory size class established after fire. Despite some qualifications, Stevens et al. However, although Stevens et al. Thus, surviving trees in high-severity fire plots were not rare based on data that they cite.
Further, Miller and Quayle [ 4 ] used plots ranging in size from 0. Thus, the plots of interest here are more likely to contain surviving trees than those of Miller and Quayle [ 4 ]. Further, Miller and Quayle [ 4 ] indicate a user and producer accuracy of But, Stevens et al. However, Stevens et al. Further, although the total footprint of subplots in FIA plots may be only 0. The FIA plots do not capture the size and shape of patches of historical fire, and do not encompass many high-severity patches, which we recognize.
But, because they are probabilistic samples, the amount of high-severity fire captured by FIA is a statistical estimate of total amount of high-severity fire. It would be a problem if high-severity fire were rare, or if only a small number of FIA plots were analyzed, but evidence for high-severity fire was abundant, and we analyzed thousands of plots.
To understand historical forest structure and fire, it is common to reconstruct the size of trees in the s by subtracting tree growth since that time e. The effects can be seen via the following general simulation. Suppose a plot was burned by high-severity fire years ago with 6. There are 5 live trees of 0. The surviving trees have a higher growth increment in earlier years which decreases as they age.
However, when the mean growth rate is calculated using mature ponderosa pine in dry forests in Oregon [ 7 ], the effects of the slower growth at old age is included to give a mean of 0.
By not considering the growth rates of surviving trees, surviving basal area at the time of the fire would be overestimated by 3. After two hundred years, the age of some FIA plots, the overestimate would be nearly 8 times the actual plot survivorship, with nearly half the basal area incorrectly considered to have survived since prior to the stand age date.
Mortality of mature trees after more recent than the stand age date could have occurred in some cases, reducing the overestimates by Stevens et al. Thus, the potential effects of high-severity fire were greatly underestimated by Stevens et al. However, DellaSala and Hanson [ 8 ]: pp.
Even though large high-severity patches may have been infrequent, they accounted for most high-severity fire [ 9 ]. However, the locations chosen by Stevens et al. The locations were mostly subjectively selected plots known to not have had severe fire in their long fire-scar history.
The plots were up to 1 km away from any FIA plots. Therefore, they do not represent the population of FIA plots we studied. In all six regions we analyzed in Odion et al. Thus, the removal of fire had a profound effect on the process of recruitment over vast areas.
Recruitment following fire suppression, as hypothesized by Stevens et al. If high-severity fire was a minor process in creating new stand ages, establishment of the dominant overstory trees would not have declined so dramatically with fire suppression. This suggestion by Stevens et al. The sources cited by Stevens et al. Additionally, Stevens et al.
In contrast, Odion et al. The concern raised by Stevens et al. This is because it is based on a different definition of high-severity fire than the classical definition used by Odion et al. The new definition proposed by Stevens et al. Using our definition or theirs of high severity, Stevens et al. Browse Subject Areas? Click through the PLOS taxonomy to find articles in your field.

What Does It Mean To Agree To Disagree?
This comparison of records is configured at design time specific to a custom application, and is based on a set of fields and their agreement and disagreement weights. OHMPI 2. The bottom-line benefit is availability of sophisticated match options that results in higher levels of granular matching and higher levels of accuracy in match results. Value substitution can be used to reduce data entry errors that cause last name and first name swapping in records. Ability to configure multiple MatchSets based on various conditions enables customers to configure powerful OHMPI solutions catering to customers' requirements for varying levels of data fields and sources of data.
We often find ourselves in disagreement with others. You may think nuclear energy is so volatile that no nuclear energy plants should be built anytime soon. But you are aware that there are many people who disagree with you on that very question. You disagree with your sister regarding the location of the piano in your childhood home, with you thinking it was in the primary living area and her thinking it was in the small den. You and many others believe Jesus Christ rose from the dead; millions of others disagree. If, in the face of all this, you stick with your belief that the piano was in the living room, will your retaining that belief be reasonable?
Language and Logic Functions of Language The formal patterns of correct reasoning can all be conveyed through ordinary language, but then so can a lot of other things. In fact, we use language in many different ways, some of which are irrelevant to any attempt to provide reasons for what we believe. It is helpful to identify at least three distinct uses of language: The informative use of language involves an effort to communicate some content. This kind of use presumes that the content of what is being communicated is actually true, so it will be our central focus in the study of logic. An expressive use of language , on the other hand, intends only to vent some feeling, or perhaps to evoke some feeling from other people.
Philosophy Introduction to Logic Let's look at a simple example of the kinds of agreement and disagreement that can arise over disputes about facts or.
Which band is the greatest of all time? Which superhero has the best superpowers? Try asking any of these questions in a room full of people. Eventually, you may have to agree to disagree. Agreeing to disagree means coming to an understanding with someone you disagree with.
There is often some confusion surrounding the terms: belief, disbelief, agreement and disagreement when used in a philosophical context. We need to keep in mind that normal dictionary definitions are often not precise enough to be used in a philosophical context where precision and clarity are essential. For analytic philosophy. Then I will suggest a new way to define the terms in the name of clarity.
A significant aspect of the import of language in everyday life is recognizing that language is used for both literal and emotional communication. Words have both a literal meaning and an emotional impact. Words with emotive significance or emotive meaning are slanted positively or negatively. All three examples exhibit a similar literal significance but differ greatly in emotive significance. Several features of this example should be noted.

More broadly, logic is the analysis and appraisal of arguments. A good argument not only possesses validity and soundness or strength, in induction , but it also avoids circular dependencies , is clearly stated, relevant, and consistent ; otherwise it is useless for reasoning and persuasion, and is classified as a fallacy. In ordinary discourse, inferences may be signified by words such as therefore , thus , hence , ergo , and so on. Historically, logic has been studied in philosophy since ancient times and mathematics since the midth century. More recently, logic has been studied in cognitive science , which draws on computer science , linguistics , philosophy and psychology , among other disciplines. A logician is any person, often a philosopher or mathematician, whose topic of scholarly study is logic. Philosophical logic is an area of philosophy.
