## Questions and Answers

My faith doesn’t give me all the answers; it gives me a way to ask the questions.

## Success

From a student essay this morning:

Somewhere in the semester I realized that everything we have gone over in class isn’t just bologna but is actually pretty applicable to life and how I can approach it.

That’s definitely a victory in freshman philosophy.

## My Oklahoma Home

My latest song:

VERSE 1:

I-40 East, on a cloudy day,

Memphis up ahead, had to get away;

Had nothing in mind

Just looking for a place to roam.

Thought I could see, but I was dumb and blind;

Gave no thought to what I left behind,

The people that I love,

and my Oklahoma home.

CHORUS:

They say that heaven’s paved

With streets of gold,

There’s no more tears

Or so I’ve been told

No more pain,

And no one feels alone.

But by those streets

Where the children play,

I hope to find

just a little red clay

To remind me

Of my Oklahoma home.

Verse 2:

Mind starts to wander when you drive for miles,

You think about faces, remember the smiles,

And you realize you’re old,

But you’ve never ever really grown.

So you turn the car into the setting sun,

The journey goes on, but the running is done.

God help me back

To my Oklahoma home.

VERSE 3:

You can’t leave, even if you tried,

When you’ve got red dirt deep down inside,

No matter how much you wanted

To leave it alone.

When you’re running away to another town,

No road is straight, they all circle around,

Bringing you back

To your Oklahoma home.

BRIDGE:

Okemah up ahead, the tears are making me blind,

And I hear the voice of Woody deep inside my mind,

And It’s taken thirty years, but now I understand,

That these are my people, and this is my land,

And these Oklahoma hills will always be home.

## Thurman on Christian Power

Too often the price exacted by society for security and respectability is that the Christian movement in its formal expression must be on the side of the strong against the weak. This is a matter of tremendous significance, for it reveals to what extent a religion that was born of a people acquainted with persecution and suffering has become the cornerstone of a civilization and of nations whose very position in modern life has too often been secured by a ruthless use of power applied to weak and defenseless peoples.

Howard Thurman, *Jesus and the Disinherited, *p.11.

## Benediction

In *The Brothers Karamazov*, Dostoevsky uses the slanting rays of the sun to represent the love of God that can flow through each of us, transforming lives as we interact with each other with genuine love.

Now, may the slanting rays of the sun

light the path before us,

as the love of God surrounds us,

to guide us on our journey.

May God guard our hearts

from anything that might separate us,

and shelter us all in his love, forever.

*Amen*

## The Art of Taxation

The art of taxation consists in so plucking the goose as to obtain the largest possible amount of feathers with the smallest possible amount of hissing.

## Truth Tables in LaTeX

Typesetting truth tables has never been easy. LaTeX is the gold standard for displaying logic and mathematics, but tables are awkward to edit at best. Tables are much simpler in Microsoft Word, but displaying formulas is a horrible experience.^{1} Here is my current workflow.

The text that I’m using this semester is *Introduction to Formal Logic with Philosophical Applications* by Russell Marcus. Instead of arrows and the ampersand, it uses the horseshoe, triple bar, and dot. So, I add the following lines to my LaTeX preamble to simplify entering the symbols.^{2}

\newcommand{\lneg}{\mathord{\sim}} \renewcommand{\land}{\bullet} \newcommand{\lif}{\supset} \newcommand{\liff}{\equiv}

Then, I enter the truth table in either Excel or Numbers. For example, this would be a simple one line table determining the truth value of a formula for a given valuation:

Copy the cells that you want included in the truth table. Go to Tables Generator, and select “LaTeX Tables” from the top menu bar. Below the top menu bar is a drop-down menu bar. Click on “File” then “Paste table data…” and paste the table data. Table Generator will generate a nicely formatted LaTeX table:

\begin{table}[] \centering \caption{My caption} \label{my-label} \begin{tabular}{llllllll} P & Q & R & P & \lif & (\lneg Q & \land & R) \\ 1 & 1 & 1 & 1 & 0 & 0 & 0 & 1 \end{tabular} \end{table}

I delete the first four lines and the last line, leaving just the table data and the lines declaring the tabular environment:

\begin{tabular}{cccccccc} P & Q & R & P & \lif & (\lneg Q & \land & R) \\ 1 & 1 & 1 & 1 & 0 & 0 & 0 & 1 \end{tabular}

At this point, typesetting will fail because the symbols need to be in math mode. So, I’ve found two options. The first is to put all the commands for the symbols in math mode:

\begin{tabular}{cccccccc} P & Q & R & P & \(\lif\) & (\(\lneg\) Q & \(\land\) & R) \\ 1 & 1 & 1 & 1 & 0 & 0 & 0 & 1 \end{tabular}

The second option is to change “tabular” to “array” and put the entire table into math mode:

\[ \begin{array}{cccccccc} P & Q & R & P & \lif & (\lneg Q & \land & R) \\ 1 & 1 & 1 & 1 & 0 & 0 & 0 & 1 \end{array} \]

Arrays are centered on the page. If you would prefer them printed at the left margin, add “fleqn” to the document class options: `\documentclass[fleqn]{article}`

Since the array is in math mode, the letters will be italicized. I use the newtxmath font package, and it has a “frenchmath” option that sets the math font to non-italic. Other math fonts may have a similar option.

Finally, whichever option is used, we need to add two lines. Adding a vertical line character to the table or array formatting options will place a vertical line between the valuation section and the rest of the truth table. Adding the booktabs package to the preamble will allow us to separate the sentence from the rest of the truth table.

This gives us the final version,

\[ \begin{array}{ccc|ccccc} P & Q & R & P & \lif & (\lneg Q & \land & R) \\ \midrule 1 & 1 & 1 & 1 & 0 & 0 & 0 & 1 \end{array} \]

which produces this:

- Apple’s Pages now allows users to add formulas with LaTeX. It’s looking like a good solution for those who like more traditional word processors. ↩
- The AMS LaTeX packages already include a command called “\lor” for entering the vee or wedge. ↩
