The first chapter of the Art of War establishes the foundational principle: warfare is not an act of impulse but of calculation. Before any engagement, the commander must assess five constant factors and seven comparative conditions. Victory belongs to the side that calculates more thoroughly. The chapter also introduces the central axiom that all warfare is based on deception.

The chapter title 始计 (Shǐjì) combines 始 (Shǐ, beginning) with 计 (Jì, calculation or planning). Some translations render this as "Laying Plans," but the Chinese emphasizes the act of assessment — counting, weighing, computing — rather than planning in the Western strategic sense.

The Five Constant Factors

Sūnzǐ identifies five factors (五事 Wǔshì) that govern warfare and must be assessed before any military decision:

Dào (道, The Way / Moral Authority) — The alignment between ruler and people. When the population shares the ruler's purpose, they will follow without fear of danger. In martial arts terms, this is the alignment between intention and action — when the mind and body share one purpose, the practitioner moves without internal conflict.

Tiān (天, Heaven) — The external conditions beyond human control: weather, seasons, day and night, timing. The practitioner who understands timing — when to advance, when to yield, when to wait — works with natural conditions rather than against them.

Dì (地, Earth) — Terrain: distances, danger, openness, narrowness. In individual combat, this is spatial awareness — controlling distance, angle, and the physical environment of the engagement.

Jiàng (将, The Commander) — The five virtues required of the leader: wisdom (智 Zhì), trustworthiness (信 Xìn), benevolence (仁 Rén), courage (勇 Yǒng), and strictness (严 Yán). In self-cultivation, these are qualities the practitioner develops in order to command his own body-mind effectively.

Fǎ (法, Method and Discipline) — Organization, structure, logistics, regulation. In training: the curriculum, the daily practice schedule, the progressive method by which skill is developed.

The Seven Comparisons

From the five factors, Sūnzǐ derives seven questions (七计 Qījì) for comparing one's own forces against the enemy's: Which ruler possesses greater moral authority? Which commander is more capable? Which side better exploits conditions of heaven and earth? Which enforces discipline more rigorously? Which army is stronger? Which has better-trained officers and soldiers? Which applies reward and punishment more consistently?

The commander who can answer these seven questions accurately can forecast the outcome before the battle begins.

Deception as Foundation

The chapter's most quoted line: 兵者，诡道也 (Bīng zhě, guǐdào yě) — "Warfare is the way of deception." When strong, appear weak. When near, appear far. When ready, appear unready. Entice with advantage. Strike disorder. Avoid strength. Provoke the irascible. These principles — collectively forming the logic of misdirection — recur throughout the text and align directly with the Wudang combat principle of concealing intention while reading the opponent's.

Connection to Wudang Practice

The five factors map naturally onto martial arts preparation. Dào is the practitioner's internal alignment — intention unified with body. Tiān is timing — sensing the moment to act. Dì is spatial control — managing distance and angle. Jiàng is the cultivated character of the martial artist. Fǎ is the training method itself.

The chapter's insistence on calculation before action mirrors the Tàijíquán principle of Tīngjìn (听劲, listening energy): before responding to force, first perceive it completely. Assessment precedes engagement. The practitioner who enters combat without having read the opponent's condition has already lost — just as the general who fights without calculation is destined for defeat.
