The following is a quote from Tom Bejgrowicz, who worked closely with Brain Fair on the overarching themes and concepts portrayed by the album. He also designed the album artwork.
The idea for The War Within turned to one man – any man, mind you – and the chaos and beauty that surrounds each of us here on earth. Birth, death, love, hate, riots, pollution, power, religion, nature, corruption of the mind, the soul, and so on. By simply living, we are open and susceptible to them all – to confront each of them, from within.
The track "Those Who Cannot Speak" is dedicated to Brian Fair's autistic niece and nephew. Fair explained in an interview:
It’s something I’ve dealt with with my niece and nephew who’ve had different forms and mild learning disabilities when it comes to speech – associating objects with language and things like that. And I also read a lot of Faulkner and he always seemed to have characters that kinda had that amazing poetry in their internal monologue but couldn’t speak. And that always intrigued me.
The War Within received positive reception on its initial release. The album debuted at position no. 20 on the Billboard 200 — the bands highest charting album. Wade Kergan of Allmusic notes that the band has grown beyond the metal-loving hardcore crowd, now having more in common with the classic thrash of Metallica. Michael Gluck of Lambgoat commented that the album "delivers itself with a fury and honoring of eighties metal guitar and vocal harmonies." In 2005, the album was ranked number 370 in Rock Hard magazine's book of The 500 Greatest Rock & Metal Albums of All Time.
The song "What Drives the Weak" received a Grammy Award nomination for Best Metal Performance in 2006, however the award went to Slipknot for the song "Before I Forget." In a 2009 MetalSucks feature titled "21 Best Metal Albums of the 21st Century... So Far", the album was listed as number 20 based on poll data from professionals in the metal industry. The editors wrote, "The Art of Balance, their third album, was solid, but The War Within was where they really hit their stride. The dual guitars of Donais and Bachand spotlighted great solos and dual harmonies that could be appreciated by both Anthrax fans and pentatonic sweep enthusiasts."
